Summary of the invention

The application provides a kind of call method and terminal device, to avoid the leakage of privacy information as far as possible, is promoted and is used The experience at family.

In order to achieve the above objectives, the embodiment of the present application adopts the following technical scheme that

In a first aspect, provide a kind of call method, this method can (for example mobile phone, ipad etc. have call by terminal device The equipment of function) it executes.This method comprises: being rung when terminal device detects the first operation for connecting the first user of incoming call The first signal should be received and be exported, and determine that terminal device is currently at the first call environment in the first operation, generate and defeated Interference signal out.Wherein, the first signal is what terminal device was obtained by the acoustic signals that the first user inputs, and interference signal is used The intelligibility for the second signal revealed when reducing terminal device and exporting the first signal, the first call environment are that easy leakage is logical Talk about the environment of content.

In this scenario, when terminal device, which determines, is currently at the environment for being easy leakage dialog context, come receiving From the first user input acoustic signals when, interference signal can be generated.And since interference signal is defeated for reducing terminal device The intelligibility for the second signal revealed when the first signal out, so the other users around terminal device can not be received from institute Second signal is correctly interpreted in the composite signal of signal, i.e. second signal and interference signal, avoids privacy letter to reach The purpose of the leakage of breath.

Second aspect, provides a kind of call method, and this method can (for example mobile phone, ipad etc. have call by terminal device The equipment of function) it executes.This method comprises: when terminal device measures the first operation for connecting the first user of incoming call, response In the first operation, sound collector is opened, is determining that terminal device is currently at the first call environment, and is collected from using When the third signal of the second user of terminal device, generates and export interference signal.Wherein, interference signal is for reducing third letter Number intelligibility.

In this scenario, the sound wave letter that the second user that third signal can be using terminal equipment is transmitted to peer user Number, when terminal device, which determines, is currently at the environment for being easy leakage dialog context, third signal is being received, can be generated dry Disturb signal.And since interference signal is for reducing the intelligibility of third signal, so the other users around second user can not From received signal, i.e., third signal is correctly interpreted in third signal and the composite signal of interference signal, avoided to reach Cause the purpose of the leakage of privacy information.

In a kind of possible design, terminal device can be currently at the first call environment based on following manner determination:

Terminal device can be with the ambient sound around acquisition terminal equipment, and detects around terminal device with the presence or absence of except the Other users except two users, if the intensity of terminal device ambient sound collected is lower than the first preset threshold, and eventually There are other users around end equipment, then can determine that terminal device is currently at the environment for being easy leakage dialog context, i.e., First call environment.

That is, can first determine whether before terminal device generates interference signal it is necessary to generate interference signal, eventually End equipment is only determining that being currently at the first call environment just generates interference signal, to mitigate the negative of terminal device as far as possible Load, reduces the energy consumption of terminal device.

In a kind of possible design, terminal device can generate interference signal based on following manner:

At least one ring for the call environment that terminal device is currently located by least one sensor acquisition terminal equipment Border parameter, and according to the mapping relations of preset environmental parameter and signal parameter value, it is determining corresponding at least one environmental parameter At least one signal parameter value, further according at least one signal parameter value generate interference signal.

In this scenario, terminal device generate interference signal, can in communication process, the call environment based on acquisition At least one environmental parameter generates corresponding interference signal, and different environmental parameters interference signal generated is also different, To obtain accurate interference signal as far as possible, the effect for avoiding the leakage of privacy information is improved.

In a kind of possible design, terminal device may also receive from the first signal of the first user, and simulate end Call environment locating for end equipment adjusts at least one signal parameter value of the first signal, until according to adjusted at least one The intelligibility of the coupled signal of interference signal and second signal that kind signal parameter value generates is lower than the second preset threshold, at this point, The corresponding relationship of at least one environmental parameter Yu at least one signal parameter value is created, mapping relations are obtained.Wherein, call environment Including at least one environmental parameter.

That is, the embodiment of the present application can receive in advance according to call environment locating for terminal device is simulated The first signal of first user, by changing the signal parameter value of the first signal, simulation generates interference signal, to obtain environment The corresponding relationship of the signal parameter value of parameter and interference signal.Since second signal is that the first signal is revealed by terminal device Go out, thus the feature of second signal and the first signal it is almost the same in this way, and in the embodiment of the present application, for reducing second The interference signal of the intelligibility of signal is obtained by changing the signal parameter value of the first signal, and such interference signal is just more Accurately.Meanwhile the mapping relations are obtained in advance, it is possible to reduce generate calculation amount when interference signal, reduce delay, help to make It obtains terminal device and relatively rapid generates interference signal, to improve the effect for avoiding leakage of private information as far as possible.

In a kind of possible design, terminal device can also acquire the third signal from second user, and simulate end Call environment locating for end equipment adjusts at least one signal parameter value of third signal, until according to adjusted at least one The intelligibility of the coupled signal of interference signal and third signal that kind signal parameter value generates is lower than third predetermined threshold value, at this point, The corresponding relationship of at least one environmental parameter Yu at least one signal parameter value is created, mapping relations are obtained.Wherein, call environment Including at least one environmental parameter；

Similarly with scheme as above, the embodiment of the present application can also determine that mapping is closed according to the third signal from second user System, the interference signal for generating the intelligibility for reducing third signal in this way is just more accurate, it is also possible to which it is dry to reduce generation Disturb calculation amount when signal, help so that terminal device relatively rapid generates interference signal, thus as far as possible improve avoid it is hidden The effect of private information leakage.

In a kind of possible design, if terminal device collects at least two environmental parameters, terminal device can be with base Interference signal is generated in following manner:

Terminal device can determine the priority of each environmental parameter of at least two environmental parameters, most further according to priority The corresponding mapping relations of high environmental parameter, determining at least one signal parameter value corresponding at least one environmental parameter, from And interference signal is generated according at least one signal parameter value.

In this scenario, terminal device is also based on component environment parameter or whole environment ginsengs in multiple environmental parameters Number is to generate interference signal, to reduce the calculation amount for generating interference signal to the greatest extent.In addition, varying environment parameter is for privacy information The influence degree of leakage is different, and the priority based on environmental parameter selects environmental parameter appropriate, further according to selected environment Parameter generates interference signal, and what the interference signal obtained in this way can accurately reduce second signal or third signal can Degree of understanding, to improve the effect for avoiding leakage of private information as far as possible.

In a kind of possible design, if the environmental parameter of terminal device acquisition includes first environment parameter, that is, it is used for Instruction other users are located at the fan-shaped region within the scope of 360 ° of terminal device, and the central angle of fan-shaped region is acute angle, then terminal If at least one signal parameter value corresponding with first environment parameter can be determined, and then periodically according at least one Signal parameter value generates interference signal.

In this scenario, for border circular areas of the fan-shaped region compared to 360 °, corresponding signal parameter value is less, in this way The signal parameter value determined based on fan-shaped region, so as to reduce the calculation amount for generating interference signal, is mitigated eventually with regard to less The burden of end equipment.In addition, periodically generating interference signal according to fan-shaped region, that is, in the single period, only for one Smaller area avoid the processing of leakage of private information, can have the effect for preferably avoiding leakage to High frequency speech signal Fruit.

In a kind of possible design, terminal device can be after exporting the first signal and the first interference signal, acquisition Fourth signal, if it is determined that the intensity of fourth signal is greater than the 4th preset threshold, then exports the first prompt information, wherein first Prompt information is used to prompt the signal parameter value in adjustment mapping relations.Wherein, fourth signal is the first interference signal and second The mixed signal of signal.

In this scenario, terminal device can acquire fourth signal, to judge that the first current interference signal is believed second Number effect interfered.If the intensity of fourth signal is larger, it may be considered that current interference signal reduces second signal Intelligibility effect it is poor, at this point, output prompt information, for reminding the signal parameter optimized for generating interference signal Value, so that signal parameter value be adaptively adjusted.

In a kind of possible design, terminal device can acquire the 5th signal, such as after exporting the second interference signal Fruit determines that the intensity of the 5th signal is greater than the 5th preset threshold, then exports the second prompt information, wherein the second prompt information is used for Signal parameter value in prompt adjustment mapping relations.Wherein, the 5th signal is the mixing letter of the second interference signal and third signal Number.

Similar with solution principle as above, what terminal device can determine that current the second interference information reduces third signal can The effect for degree of understanding, if it is determined that the effect that the second interference information reduces the intelligibility of third signal is poor, then can export prompt Information, to prompt user optimization for generating the signal parameter value of the second interference signal.

In a kind of possible design, terminal device can also be in the second operation for detecting input, in response to second Operation, display reminding interface, and when detecting the third operation for adjustment option input, it operates, will reflect in response to third The signal parameter value penetrated in relationship is adjusted to the indicated value of third operation.Wherein, the second operation is for requesting adjustment mapping Signal parameter value in relationship, prompting interface include adjustment option, and adjustment option is used to indicate the signal parameter in mapping relations The value range of value, third operation are used to indicate the value selected respectively in the value range of each signal parameter value.

For terminal device below with reference to structure shown in Fig. 4, in conjunction with attached drawing to the call method of the embodiment of the present application into Row detailed description.

By taking user A initiates calling to user B by terminal device 100-1 as an example.Please continue to refer to Fig. 2, work as terminal device 100-1 detects that user A clicks the dialing button in the user interface (user interface, UI) 200 of terminal device 100-1 When 201, terminal device 100-1 initiates to call in response to the operation to dialing button 201, to user B, and shows on a display screen User interface 202 as shown in Figure 2.The call signal that terminal device 100-1 is initiated is transferred to the example in mobile communications network Such as base station, base station is connected to the terminal device 100-2 that user B is used, at this point, terminal device 100-1 and terminal device 100-2 is established Play communication connection.

When user A talks against terminal device 100-1, the vibrational excitation air vibration of vocal cords forms acoustic signals, hereafter In, which is known as the first signal.

After microphone 440C or receiver 440B in terminal device 100-1 collect the first signal, the first signal is turned Current signal is turned to, current signal is encoded by coding/decoding module, is then modulated encoded signal by modulation /demodulation module Mobile communications network is sent to by mobile communication module 431 or wireless communication module 432 at radiofrequency signal, via mobile communication Network transmission gives terminal device 100-2.Radiofrequency signal is demodulated to coding letter by the modulation /demodulation module in terminal device 100-2 Number, then processing is decoded to encoded signal by coding/decoding module, obtains current signal, then (i.e. by loudspeaker 440A or earpiece Receiver 440B) etc. sounding components convert acoustic signals for received current signal and export, such user B is set by terminal The earpiece or loudspeaker 440A of standby 100-2 can uppick user A speech.Hereinafter, terminal device 100-2 is received Signal from user A is known as second signal.

For terminal device 100-2 when exporting second signal, second signal may be via at the top of terminal device 100-2 or side Gap leak out, so as to cause the leakage of privacy information.Hereinafter, it is leaked when terminal device 100-2 being exported second signal Signal be known as third signal.

In order to avoid the leakage of privacy information, can be given birth in terminal device 100-2 when receiving the voice signal of user A At for interfering the interference signal of third signal, to reduce the user around user B to the intelligibility of third signal, or even reduce User around user B hears a possibility that speech content of user A.The intelligibility of third signal can be understood as believing third Number identification, for example, the intensity of third signal is lower, then a possibility that user around user B hears third signal compared with It is low, so that the content possibility for correctly interpreting third signal is lower, i.e., it is relatively low to the identification of third signal.In another example such as Fruit third signal is masked in the time domain or on frequency domain, lacks then the useful information of the third signal can exist to a certain extent It loses, in this case, the identification of third signal is relatively low.

Terminal device 100-2 can generate the first interference signal for interfering third signal based on second signal, and defeated First interference signal out.Wherein, second signal can be by a sounding component on terminal device 100-2, such as one is listened Cylinder output, and the first interference signal can be by another sounding component of terminal device 100-2, such as another earpiece exports. Synthesis when can propagate in air from the terminal device 100-2 third signal revealed and the first interference signal forms the 4th letter Number, to be transferred to the other users around user.Since second signal is the hair by such as earpiece on terminal device 100-2 Sound component output, user B directly receive second signal by earpiece, will not influence the interpretation to second signal.But first is dry Interference can be formed to third signal by disturbing signal, so the first interference signal reduces the identification of third signal, to drop The intelligibility of other users around low user B to third signal.For example, the first interference signal if it is with third signal The signal of opposite in phase, then the intensity for the fourth signal that the first interference signal and third signal are formed is compared to third signal Intensity becomes smaller, that is, the amplitude of fourth signal is lower than the amplitude of third signal, and the user that can be reduced around user B hears A possibility that speech content of user A, to reduce the other users around user B to the intelligibility of third signal.In another example First interference signal can cause time domain masking to third signal, then the other users around user B receive third signal, Whole useful informations can not be obtained from third signal, thus reduce other users around user B to third signal can Degree of understanding.

In the embodiment of the present application, using the received second signal of terminal device 100-2 as the first interference signal of generation Basis signal, do not need that the basis signal for generating the first interference signal is in addition separately provided in this way.And usually, Third signal is that second signal is leaked out by terminal device 100-2, the basic phase of feature of third signal and second signal Together, the first interference signal of interference third signal is generated based on second signal, more targetedly, the first interference signal of generation can Preferably to interfere third signal.For example, terminal device 100-2 when receiving second signal, is based on second signal in real time The first interference signal is generated, is exporting the first interference signal later.Second signal and the first interference signal in this way is almost defeated simultaneously Out, the intelligibility of third signal can be reduced in real time.

In addition, if when reducing user to the intelligibility of third signal, with third signal for above-mentioned basis signal, i.e., Interference signal is generated according to third signal itself, then just needing to acquire third signal in real time, to the real-time of signal processing It is more demanding.And the application does not need to acquire third signal in real time, to signal using received second signal as basic signal The requirement of real-time of processing is lower.

Illustratively, the first interference signal may include the time delayed signal of second signal, for ease of description, hereinafter, The time delayed signal of second signal is known as audio signal；Alternatively, the first interference signal may include the time domain overturning of second signal Signal, hereinafter also referred to as time domain masking signal；Alternatively, the first interference signal may include the turbulence in frequency domain letter of second signal Number, hereinafter also referred to as frequency domain masking signal, or, the first interference signal can be harmonic signal etc..It only enumerates above Four kind of first interference signal, as long as the signal that can actually reduce the intelligibility of third signal can be with for example, first At least two first interference signals that interference signal is also possible in above-mentioned four kind of first interference signal are superimposed the signal to be formed, this Apply embodiment to this with no restriction.

In order to make it easy to understand, referring to Fig. 6, being the transmission schematic diagram of second signal provided by the embodiments of the present application.Fig. 6 with Terminal device 100-2 is arranged for two sounding components, wherein sounding component 1 is used for generating second signal, sounding component 2 In generating the first interference signal.In Fig. 6, signal S is second signal, and signal X is third signal, and signal Y is the first interference letter Number, signal D is second signal, the i.e. composite signal of third signal X and the first interference signal Y.From fig. 6 it can be seen that third Signal, that is, signal X is propagated after the ear reflection of user B in air after terminal device 100-2 output.First interference Signal Y is for reducing the signal of the intelligibility of third signal X, as shown in fig. 6, being and third signal X with the first interference signal Y For the signal of opposite in phase.From fig. 6 it can be seen that amplitude of the amplitude of fourth signal D lower than third signal X, i.e., first The remitted its fury that interference signal makes the amplitude reduction of third signal X namely the first interference signal Y make third signal X, thus Reduce a possibility that other users around user B catch third signal X.User around user B in this way receives the 4th When signal D, it is more difficult to third signal X is interpreted from fourth signal D, so that the user reduced around user B listens to third signal X Correct interpretation a possibility that, achieve the purpose that avoid user voice leakage of private information.

In fact, different call environments also owns the influence degree of the leakage of the privacy information of terminal device 100-2 It is different.For example, terminal device 100-2 in elevator, since lift space is relatively narrow, and has echo, then privacy information is let out A possibility that dew, is larger.Opposite, terminal device 100-2 is on square, due to square space opposing open, leakage of private information A possibility that it is just smaller.In another example even at identical call place, between the other users and user B around user B Distance is different, to the influence degree of the leakage of privacy information also all differences.For example, the distance between other users and user B Relatively close, then larger a possibility that leakage of private information, conversely, the distance between other users and user B are farther out, then privacy is believed A possibility that breath leakage, is smaller.For another example other users are different from the relative position of user B, to the shadow of the leakage of privacy information The degree of sound also all differences.For example, user B answers the acoustic signals of terminal device 100-2 output by auris dextra, work as other users Positioned at the right side of user B, a possibility that leakage of private information, is larger, conversely, other users are located at the left side of user B, privacy letter A possibility that breath leakage, is smaller.

In view of influence degree of the different call environments to the leakage of the privacy information of terminal device 100-2 is different, this Apply for that the terminal device 100-2 in embodiment can generate corresponding first according to terminal device 100-2 current call environment Interference signal, to reduce the intelligibility of third signal as far as possible.

Specifically, terminal device 100-2, when connecting the dial-up of terminal device 100-1, terminal device 100-2 can be with The call environment that detection terminal device 100-2 is presently in.Here call environment can be leads to locating for terminal device 100-2 It talks about on scene (such as elevator, square etc.), the distance between other users and the user B being also possible to around user B, alternatively, Distance etc. of the ear apart from terminal device 100-2 that can be user B, will not enumerate here.Certainly, call here Environment is also possible to any combination of above-mentioned three enumerated kind call environment, and the embodiment of the present application does not make the combination of call environment Limitation.

Illustratively, terminal device 100-2 can open camera when connecting the dial-up of terminal device 100-1, And receive image captured by camera.Terminal device 100-2 can determine the object around user B according to captured image It is other users or other objects (such as building).Meanwhile terminal device 100-2 can also be according to captured by camera Image determine that place where terminal device 100-2 is the narrow place of space (such as elevator, meeting room) or space The place (such as square) of opposing open.In order to more accurately determine the environment around terminal device 100-2, camera shooting here Head can be the camera that the camera lenses such as similar above-mentioned camera 453B and camera 453D are anamorphic lens.Work as terminal device in this way 100-2 can shoot wide picture image, help so that and show more contents in the image of shooting.

Illustratively, terminal device 100-2 can also be opened thereon when connecting the dial-up of terminal device 100-1 The range sensor 460F of setting, and receive the distance signal detected from range sensor 460F.Terminal device 100-2 according to Distance signal can determine the distance between other users and user B around user B.

Illustratively, terminal device 100-2 can also be opened thereon when connecting the dial-up of terminal device 100-1 Be arranged close to optical sensor 460G, and receive the electric signal for detect close to optical sensor 460G.Terminal device 100-2 according to The electric signal can determine the distance between ear and terminal device 100-2 of user B.

For simplicity, the above-mentioned call environment for only listing terminal device 100-2 detection terminal device 100-2 and being presently in Three kinds of specific embodiments.In fact, the embodiment of the present application terminal device 100-2 detection terminal device 100-2 is presently in Call environment can be any two kinds or three kinds in above-mentioned three kinds of specific embodiments of combination, the embodiment of the present application is to this With no restriction.It, can be according to determining when terminal device 100-2 has determined the call environment that terminal device 100-2 is presently in Call environment generate corresponding first interference signal.

For example, the embodiment of the present application can simulate second signal in advance, and second signal based on simulation generation first is dry Signal is disturbed, and determines the signal parameter value of the first interference signal.Here signal parameter value can consider the property parameters of signal Value.Here property parameters may include at least one of phase, amplitude, frequency, delay in time domain etc..Different is logical Words environment correspond to the first different interference signals, the corresponding one group of property parameters of first interference signal, that is, different leads to Words environment corresponds to the value of each property parameters in one group of different property parameters.

Specifically, terminal device 100-2 can be placed in different call environments by the embodiment of the present application in advance, and simulate use Family A is conversed by terminal device 100-1 and the user B of using terminal equipment 100-2.In the earpiece of terminal device 100-2 When equal sounding components receive the second signal that user A is inputted by terminal device 100-1, terminal device 100-2, which passes through to remove, to be somebody's turn to do Sounding component except earpiece exports the first interference signal, and is tested, (the user around user B at test position C) amplitude of received fourth signal or intelligibility are lower than the first preset threshold, record the parameter of the first interference signal at this time Value.

In a kind of possible embodiment, the embodiment of the present application can modify the second letter by way of deep learning Number at least one property parameters, it is dry to obtain first and according to modified at least one property parameters training second signal Signal is disturbed, until resulting first interference signal of training makes the amplitude of the signal at test position or intelligibility pre- lower than first If threshold value.At this point, obtaining the signal parameter value of the first interference signal.

It should be noted that corresponding first preset threshold of the amplitude of the signal at test position, at test position Corresponding first preset threshold of the intelligibility of signal may be identical, it is also possible to different.

Illustratively, user B hand-held terminal device 100-2 is in one jiao (being assumed to be vertex A) of elevator, works as terminal device When 100-2 is on call, the intensity that elevator is located at the acoustic signals at B point and C point position is acquired respectively.Wherein, B point is It is with the adjacent vertex on one side with top A point, the line of C point and vertex A are the diagonal lines of elevator.Usually, when user listens When the intensity of the acoustic signals arrived is lower than the first preset threshold, user can not correctly interpret acoustic signals.So in the application reality It applies in example, sounds the second signal of self terminal equipment 100-1 when the A that user B hand-held terminal device 100-2 is in elevator is checked and accepted When, at least one property parameters of second signal, and training second signal can be modified.Resulting first interference after training every time Signal is exported via sounding component, and is superimposed during air borne with third signal and is formed fourth signal output, until surveying The amplitude or intelligibility of fourth signal of the examination in B point or C point are lower than the first preset threshold, record training second signal pair at this time The signal parameter value answered.

In another example user B hand-held terminal device 100-2 is in square, in multiple positions around acquisition user B Any one position, when user's B hand-held terminal device 100-2 is listened to from the second signal of terminal device 100-1, modification the At least one property parameters of binary signal, and training second signal, resulting first interference signal after training second signal Amplitude or intelligibility with third signal in the fourth signal of any one above-mentioned position synthesis are lower than the first preset threshold, at this time Record the corresponding signal parameter value of training second signal.

Above-mentioned two example be only under same call scene, based on other users and the user B around user B away from For determining signal parameter value corresponding with the first interference signal, in the specific implementation process, the embodiment of the present application can be with thing Simulation test first is carried out for a variety of call environments, to obtain signal parameter value corresponding with the first interference signal.

Illustratively, it is identical at a distance from user B to be also based on the other users around user B for the embodiment of the present application In the case of, simulation test is carried out for different call scenes, obtains signal parameter value corresponding with the first interference signal.

For example, when user B hand-held terminal device 100-2, due to the difference of personal use habit, the ear of some users from Terminal device 100-2 is closer, and farther out from terminal device 100-2, and the ear of user is from terminal device for the ear of some users The difference of the distance of 100-2 causes the first interference signal also different.So the embodiment of the present application can be in same call Under scene, the other users around user B are in identical situation at a distance from user B, respectively for the ear of user B from terminal In the case that the distance of equipment 100-2 is different, at least one property parameters of second signal, and training second signal are modified, from And obtain signal parameter value corresponding with the first interference signal.

In another example due to other features of second signal, such as second signal is male voice sound wave letter as another embodiment Number or second signal be schoolgirl's acoustic signals, corresponding first interference signal may also be different.Or second letter It number is English acoustic signals or Chinese acoustic signals, corresponding first interference signal may also be different.So the application Embodiment can be tested when determining the signal parameter value of the first interference signal with different types of second signal.For example, It for same call environment, is tested respectively with boy student's acoustic signals and schoolgirl's acoustic signals, obtains corresponding first interference Signal, then determine signal parameter value corresponding with the first interference signal.Here call environment can refer to call scene and/or use Other users around the B of family are at a distance from user B etc..

In another example the other users around user B may be dispersed within the scope of 360 ° around user B, it is also possible to only In some angular regions around user B, as shown in Figure 7.Fig. 8 is with there are 3 other users (such as Fig. 7 institute around user B The 3 user C shown) for, it can be seen from figure 7 that 3 other users C are located within the scope of the region A around user B, region A is the fan-shaped region that central angle is 90 °.For ease of description, other users are hereinafter located at the region around user B to be known as Target area.

Usually, target area is bigger, and the type of the property parameters of training second signal is more, and complexity is higher, keeps away The effect for exempting from leakage of private information is poorer.And terminal device 100-2 generates the first interference signal based on more property parameters When, occupying system resources are also more.

Under the circumstances, in order to reduce the complexity of property parameters, and the effect of leakage of private information is improved, this Shen Please embodiment be also based on target area selectively train second signal property parameters, rather than training second signal Whole property parameters, the type of property parameters trained in this way is less, reduces complexity.

Specifically, the corresponding property parameters in different target areas are also different.The embodiment of the present application can prior mould The relative positional relationship of quasi- other users and user B, that is, simulate multiple target areas.For each target area of simulation, The embodiment of the present application can modify part property parameters or whole attribute ginsengs at least one property parameters of second signal Number, and training second signal, the 4th letter that the first interference signal and third signal obtained after training synthesizes at test Number intelligibility less than the first preset threshold.

Illustratively, for different target areas, the property parameters of trained second signal may also be different, obtains To the first interference signal prevent privacy information leakage effect also all differences.For example, the first object area around user B Domain corresponds to first group of property parameters, the corresponding second group of property parameters in the second target area around user B, first group of property parameters Different from second group of property parameters, first group of property parameters is more compared to second group of property parameters type, then passing through first group The first interference signal that property parameters training second signal obtains prevents compared to second group category of effect of the leakage of privacy information The first interference signal that property parameter training second signal obtains prevents the effect of the leakage of privacy information more preferable.

The embodiment of the present application can determine corresponding property parameters based on target area, and since the region of consideration is smaller, The property parameters of selection may be less, so the complexity of training property parameters reduces.Meanwhile target area is exactly other use Family region, so there is specific aim based on the property parameters that target area obtains, compared to based on 360 ° around user B The property parameters that range determines, can be further improved the effect for avoiding leakage of private information.

It should be noted that in the specific implementation process, the embodiment of the present application can have previously been based on one of call environment Environmental parameter or multiple environmental parameters carry out simulation test, to obtain signal parameter value corresponding with the first interference signal.This In environmental parameter refer to call scene, the other users around user B with user B at a distance from, the ear of user B distance end Distance, the type of second signal of end equipment 100-2, naturally it is also possible to be other possible environmental parameters, for example, other users It is in the left side of the ear of user B or right side etc..

The embodiment of the present application has determined the signal parameter value of the first interference signal, can establish call environment and the first interference The mapping relations of the signal parameter value of signal are also possible to establish reflecting for environmental parameter and the signal parameter value of the first interference signal Penetrate relationship.The mapping relations can store in terminal device 100-2, and such terminal device 100-2 can be based on current true Fixed call environment and the mapping relations select corresponding property parameters to generate the first interference signal.

Specifically, in view of in call environment, varying environment parameter to the influence degree of leakage of private information also it is all not Together.The embodiment of the present application, can be based on to leakage of private information when selecting property parameters corresponding with the first interference signal The priority of influence degree determines, without considering whole environmental parameters, selects relatively simple property parameters as far as possible, To save the energy consumption of terminal device 100-2.

Different environmental parameters may correspond to different signal parameter values, that is, correspond to different property parameters, i.e., not With environmental parameter may corresponding first interference signal also all differences.It in the embodiment of the present application, in advance can be according to not Same environmental parameter establishes multiple mapping relations.For example, environmental parameter indicates enclosure space, then the first mapping relations are corresponded to, the The corresponding property parameters of one mapping relations may be amplitude；Environmental parameter indicates open space, then corresponds to the second mapping relations, the The corresponding property parameters of two mapping relations may be phase.In another example environmental parameter instruction other users and user B between away from It is close from relatively, then third mapping relations are corresponded to, the corresponding property parameters of third mapping relations may be frequency domain；Environmental parameter indicates it The distance between his user and user B farther out, then correspond to the 4th mapping relations, the corresponding property parameters of third mapping relations may It is time domain.Certainly, above-mentioned is only citing, and environmental parameter can be multiple, such as environmental parameter indicates enclosure space, and indicates it The distance between his user and user B are relatively close, then correspond to the 5th mapping relations, the corresponding property parameters of third mapping relations may It is frequency domain and amplitude.The above is only citings, do not limit actual corresponding relationship.

The embodiment of the present application can determine the priority of multiple environmental parameters of call environment in advance.For example, due to elevator Space is relatively narrow and has echo, and in this case, call scene is relative to other environmental parameters (such as class of second signal Type) for, it is larger to the influence degree of leakage of private information.At this point, the priority of elevator is higher than the excellent of the type of second signal First grade.In another example due to square space opposing open, in this case, call scene is relative to other environmental parameters (such as the The type of binary signal) for, it is smaller to the influence degree of leakage of private information.At this point, the priority on square is lower than second signal Type priority.Or identical call scene, the distance between other users and user B are relative to other environment It is larger to the influence degree of leakage of private information for parameter (such as type of second signal).At this point, other users and user The priority of the distance between B is higher than the priority of the type of second signal.

After the embodiment of the present application is ranked up the priority of multiple environmental parameters of call environment, determined based on current Call environment and each environmental parameter priority, selected and the environmental parameter of highest priority from multiple mapping relations Corresponding mapping relations, to generate the first interference signal according to selected mapping relations.In order to make it easy to understand, below with difference Call environment introduce terminal device 100-2 how Choose for user relationship, generate the first interference signal.

The first call environment: there are also other users in elevator and elevator, and second signal is schoolgirl's acoustic signals.

Terminal device 100-2 determines that the environmental parameter of current call environment is the type of call scene and second signal, And call scene is elevator, terminal device 100-2 is using the higher elevator of priority as base condition at this time, selection and elevator pair The mapping relations answered.

Alternatively, in some instances, terminal device 100-2 is using the type of the higher second signal of priority as datum strip Part.For example, terminal device 100-2 can determine that user B is boy student or female based on frequency information of the user B in communication process It is raw, it is marked in address list in advance, so that terminal device 100-2 can when user's B using terminal equipment 100-2 converses To judge that user B is schoolgirl, mapping relations corresponding with schoolgirl's acoustic signals are selected.

Second of call environment: there are multiple other users in square and square, this multiple other users and user B away from Have closely from having far.

Terminal device 100-2 determines that the environmental parameter of current call environment is call scene and second signal, and converses Scene is square, at this time terminal device 100-2 using the higher other users of priority at a distance from user B as base condition, Selection with apart from corresponding mapping relations.

Above two call environment only can actually include two or more environment for including two kinds of environmental parameters Parameter.When call environment includes two or more environmental parameter, the embodiment of the present application is joined based on the environment under same priority The priority of another environmental parameter under several determines mapping relations, the selection method under specific similar above two call environment, Which is not described herein again.

Certainly, the embodiment of the present application, can also be based in call environment in order to guarantee to avoid leakage of private information as far as possible Whole environmental parameter Choose for user relationships generate the first interference signal based on more property parameters.

For example, referring to Fig. 8, Fig. 8 is the transmission schematic diagram of second signal provided by the embodiments of the present application.Fig. 8 is with terminal For current talking environment locating for equipment 100-2 is the first above-mentioned call environment.Second signal is signal S, terminal in Fig. 8 Equipment 100-2 selects mapping relations the first interference signal (signal Y1 as shown in Figure 8) generated corresponding with elevator, in sky Fourth signal (signal as shown in Figure 8 can be formed after being superimposed upon in third signal (signal X1 as shown in Figure 8) by propagating in gas D1), as can be seen from Figure 8 the intensity of signal D1 is lower.In order to be distinguished with signal D2 hereinafter, it is assumed here that signal The amplitude or intelligibility of D1 is lower than the second preset threshold.And terminal device 100-2 comprehensively considers the second signal of elevator and Chinese, Mapping relations the first interference signal (signal Y2 as shown in Figure 8) generated corresponding with elevator and second signal is selected, After being superimposed upon in third signal (signal X2 as shown in Figure 8), the intensity of the fourth signal (signal D2 as shown in Figure 8) of formation Lower than third predetermined threshold value, wherein third predetermined threshold value is lower than the second preset threshold.

In a kind of possible embodiment, the highest priority of target area, in this case, terminal device 100-2 It, can camera and range sensor to be arranged on opening terminal apparatus 100-2 when connecting the dial-up of terminal device 100-1 Deng determining target area of the other users with respect to user B.After terminal device 100-2 has determined target area, it is based on and target The corresponding mapping relations in region generate the first interference signal, alternatively, terminal device 100-2 is based on target area and other rings Border parameter determines mapping relations, and generates the first interference signal based on determining mapping relations, avoids privacy information to realize Leakage.

When being in communication process in view of terminal device 100-2, terminal device 100-2 also exists with the movement of user B It is mobile, then call environment locating for terminal device 100-2 also agrees to change.For example, terminal device 100-2 is with user B may be moved to open space from enclosure space, it is also possible to be moved to no other users from the environment there are other users and exist The environment of surrounding.So the embodiment of the present application in communication process, can in real time or periodically determine current call Environment, adaptively to adjust selected mapping relations according to currently determining call environment, to be better protected from privacy letter The leakage of breath.

It illustratively, is target area with call environment, the embodiment of the present application can periodically determine target area, with Selected mapping relations are adaptively adjusted, that is, adjust the first interference signal, improve the protecting effect of privacy information.

Fig. 9 is referred to, Fig. 9 is the transmission schematic diagram of second signal provided by the embodiments of the present application.Fig. 9 is in terminal device During 100-2 is on call, the relative position of other users (user C as shown in Figure 9) and user B around user B is sent out It changes and turns to example.It can be seen in figure 9 that terminal device 100-2 passes through the sensor that is arranged thereon (such as range sensor Deng) determine that user C is moved to target area B from target area A, then mapping relations used by terminal device 100-2 is adjusted, Currently employed mapping relations are adjusted to mapping relations corresponding with target area B.Target area A and target area in Fig. 9 Domain B is illustrated with dotted line line of demarcation.For the ease of distinguishing, first based on the corresponding mapping relations generation of target area A is dry Disturbing signal is signal Y1 shown in Fig. 9, and the first interference signal generated based on the corresponding mapping relations of target area B is Fig. 9 institute The corresponding third signal of the signal Y2 shown, target area A is signal X1 shown in Fig. 10, the corresponding third signal of target area B For signal X2 shown in Fig. 9.Signal Y1 and signal Y2 may it is identical may also be different, Fig. 9 is with the amplitude of signal Y1 and signal Y2 Amplitude it is not identical for.

Certainly, target area may be the region of 360 ° of ranges around user B.If target area is around user B 360 ° of ranges region, then the complexity of property parameters corresponding to the corresponding mapping relations in target area is higher, terminal When equipment 100-2 is based on mapping relations the first interference signal of generation, occupied system resource is more, and the used time is longer.And if eventually End equipment 100-2 is likely to be under more complicated reflection environment, and in this case, the radio-frequency component of third signal exists more Complicated superposition, and high-frequency signal is since wavelength is shorter, it, can only if the intensity in a wide range of for third signal is eliminated It realizes in specific position to the elimination of the intensity of third signal, thus is avoided that the effect of leakage of private information is poor.

In consideration of it, being the region of 360 ° of ranges around user B for target area as another possible embodiment The case where, target area can be divided into multiple sub-goal regions by the embodiment of the present application.One sub- target area is corresponding to be reflected The corresponding one group of property parameters of relationship are penetrated, terminal device 100-2 can periodically use attribute corresponding with the sub-goal region Parameter generates the first interference signal, that is, periodically generates the first interference signal.It is directed to a sub- target area in this way, being located at should The other users in sub-goal region receive fourth signal, and third signal can not be interpreted from fourth signal.Or even by Lower in the intensity of fourth signal, the other users positioned at the sub-goal region can not receive fourth signal.And when next Between section, i.e., for for another sub-goal region adjacent with the sub-goal region, positioned at its of another sub-goal region His user can not interpret third signal from fourth signal, or even can not receive fourth signal.That is, in the single period, Avoid only for a sub- target area processing of leakage of private information, in other times section, using corresponding sub-goal area The corresponding property parameters in domain avoid the processing of leakage of private information, and the region of 360 ° of ranges around user B can be realized The processing for avoiding leakage of private information.In this way, carrying out avoiding privacy in smaller area for a sub- target area every time The processing of information leakage can have the effect of High frequency speech signal preferably avoiding leakage.The embodiment of the present application is with default Scanning speed scan each sub-goal region, can reduce the height of the third signal in the region of 360 ° of ranges around user B The intelligibility of frequency ingredient.

Specifically, referring to Figure 10, for the schematic diagram of second signal provided by the embodiments of the present application transmission.Terminal device 100-2 can be scanned the peripheral region user B using preset scanning speed when generating the first interference signal.It is based on The corresponding mapping relations in the first sub-goal region (region A as shown in Figure 10) that preliminary sweep arrives generate the first interference signal (signal Y1 as shown in Figure 10) is propagated be superimposed upon the 4th letter of third signal (signal X1 as shown in Figure 10) formation in air The intensity of number (signal D1 as shown in Figure 10) is lower than some threshold value, such as the 4th preset threshold.It successively scans to the second specific item It marks region (region B as shown in Figure 10), generates the first interference signal (such as based on the corresponding mapping relations in the second sub-goal region Signal Y2 shown in Fig. 10), it propagates be superimposed upon third signal (signal X2 as shown in Figure 10) formation fourth signal in air The intensity of (signal D2 as shown in Figure 10) is also below some threshold value, such as the 5th preset threshold.Third specific item is arrived in scanning later It marks region (region C as shown in Figure 10), generates the first interference signal (such as based on the corresponding mapping relations in the second sub-goal region Signal Y3 shown in Fig. 10), it propagates be superimposed upon third signal (signal X3 as shown in Figure 10) formation fourth signal in air The intensity of (signal D3 as shown in Figure 10) is also below threshold value, such as the 6th preset threshold, until terminal device 100-2 is arrived in scanning End of conversation.Wherein, above-mentioned 4th preset threshold, the 5th preset threshold and the 6th preset threshold may be identical, it is also possible to and it is different, As long as the user around user B, which is based on the 4th preset threshold, the 5th preset threshold and the 6th preset threshold, cannot correctly solve Read third signal.It should be noted that the 4th preset threshold, the 5th preset threshold and the 6th preset threshold are merely to more Explanation figure 10 well, and do not have limiting meaning.

It should be noted that the embodiment of the present application to the quantity and area in multiple sub-goal regions with no restriction.Specifically , quantity or area for sub-goal region complexity based on property parameters and can avoid leakage of private information Effect determines, for example, the quantity in multiple sub-goal regions can be 6, multiple sub-goals in a kind of possible embodiment The area in region can be identical, be also possible to different.

Terminal device 100-2 in the embodiment of the present application can pass through built-in Digital Signal Processing (Digital Signal Processing) chip or other possible signal generating devices are based on second signal and mapping relations, i.e. ring The signal parameter value of border parameter and the first interference signal generates the first interference signal.Dsp chip can be by the first interference of generation Signal is transferred to the sounding component of similar earpiece being arranged on terminal device 100-2 etc..A hair of terminal device 100-2 in this way Set earpiece can export second signal on sound component, such as terminal device 100-2, another sounding component can export The first interference signal.

The sounding component of terminal device 100-2 setting in the embodiment of the present application can be one or more earpieces, or The sounding component of similar earpiece.Side opposite with microphone on the terminal device can be set in one or more sounding components, For ease of description, the side that microphone is hereinafter referred to as arranged is known as the bottom of terminal device, then the side opposite with bottom Referred to as top.Alternatively, one or more sounding components can be set at the back side (one side opposite with display screen) of terminal device, Or some sounding components are arranged at top, the back side of terminal device is arranged in some sounding components.

It should be noted that if terminal device 100-2 is by the sounding component other than the earpiece that itself is arranged The first interference signal is exported, then terminal device 100-2 preferentially selects the sounding component of the earpiece close to terminal device 100-2 defeated First interference signal out.For example, sounding component is arranged in terminal device if the top of terminal device 100-2 is arranged in earpiece The back side of terminal device 100-2 is arranged in close to the sounding component of the position at top then preferably selecting in the back side of 100-2.Hair Sound component is relatively close from earpiece (sound source), and such sounding component and earpiece are closer to the transmitting situation of acoustic signals, and first The property parameters of interference signal are that training obtains using earpiece as sounding component, it is possible to improve avoid privacy information as far as possible The effect of leakage.

In above-described embodiment, terminal device 100-2 connects the dial-up from terminal device 100-1 or receives When the second signal of self terminal equipment 100-1, call environment locating for terminal device 100-2 is just detected, and according to detected Call environment generates the first interference signal.But if terminal device 100-2 is answered under relatively noisy environment and is carried out self terminal The call of equipment 100-1 can reduce third then the noise in environment inherently causes certain interference to third signal A possibility that intelligibility of signal, the other users near user B hear acoustic signals at this time, is lower.In this case, terminal Equipment 100-2 can not need to generate the first interference signal, with the energy consumption for the terminal device 100-2 that practices every conceivable frugality.

As another embodiment, terminal device 100-2, can be with when connecting from the dial-up of terminal device 100-2 The noise of environment where detecting terminal device 100-2, to determine whether generation first according to the size of detected noise Interference signal.For example, terminal device 100-2 can store ambient noise threshold, such as 80dB in advance, as terminal device 100-2 The ambient noise for being currently located environment is greater than or equal to ambient noise threshold, it may be considered that terminal device 100-2 is currently located Environment is more noisy, and otherwise it is more quiet to be currently located environment by terminal device 100-2.When terminal device 100-2 determines current institute It is more noisy in environment, then generate the first interference signal.

Illustratively, when terminal device 100-2 is connected from the calling of terminal device 100-1, it can star terminal and set Set for example above-mentioned microphone 440C acquires acoustic signals on standby 100-2, and acoustic signals here may be only from end The noise of environment where end equipment 100-2, it is also possible to the noise from environment where terminal device 100-2, and to use by oneself The acoustic signals of family B.The acoustic signals of acquisition can be sent to processor 410 by microphone 440C, and processor 410 analyzes sound wave Signal, the size of the noise of environment where determining terminal device 100-2.

When terminal device 100-2 is in communication process, environment where terminal device 100-2 may change, example Such as, terminal device 100-2 is as the movement of user B is also in movement.So coming from terminal device when terminal device 100-2 is connected After the calling of 100-1, the processor 410 of terminal device 100-2 can periodically analyze microphone 440C sound wave collected Signal relatively accurately determines that terminal device 100-2 is currently located the noise size of environment with as far as possible.Meanwhile terminal device 100-2 can be currently located the noise size of environment according to periodic detection terminal device 100-2, and adaptability is opened for giving birth to At the signal generating device such as dsp chip of the first interference signal, always on terminal device 100-2 may not be needed in this way Signal generating device, to save the energy consumption of terminal device 100-2.

In another embodiment, what the embodiment of the present application can store terminal device 100-2 interferes for generating first The mapping relations of signal are updated, to improve a possibility that avoiding leakage of private information as far as possible.

Specifically, terminal device 100-2, which can be used, is located at the sound such as microphone set by the back side terminal device 100-2 The third signal of the sounding component output of collector acquisition terminal equipment 100-2 and the composite signal of the first interference signal, i.e., the Four signals.The intensity of the fourth signal of acquisition is compared by terminal device 100-2 with preset threshold, to determine fourth signal Whether intensity meets preset condition.For example, preset threshold can be the more appropriate volume value that user B can be heard, and distance The volume value that user in user's B preset range can't hear.If terminal device 100-2 is big by the intensity of the fourth signal of acquisition In preset threshold, then it is assumed that a possibility that volume of fourth signal is larger, and the other users around user B hear the fourth signal It is larger.In this case, terminal device 100-2 can update the mapping relations for generating the first interference signal, so that the The intensity of four signals is less than preset threshold.

Illustratively, terminal device 100-2, which can be used, is located at the sound such as microphone set by the back side terminal device 100-2 Sound collector acquires fourth signal, to judge that the other users around user B are interpreted according to the size of the volume value of fourth signal The size of a possibility that third signal.If the volume value of fourth signal is greater than preset threshold, then it is assumed that other around user B It is larger that user interprets a possibility that third signal, at this point, terminal device 100-2 can export prompt information, which is used Signal parameter value in prompt adjustment mapping relations.In possible embodiment, prompt information can be voice prompting letter Breath, is also possible to text prompt information, in the embodiment of the present application, is not construed as limiting to this.

Terminal device 100-2 is detecting user for requesting the input operation of the signal parameter value in adjustment mapping relations When, input operation is responded, can show adjustment option in the display interface.The adjustment option can indicate in mapping relations The value range of each signal parameter value, to provide the foundation of the signal parameter value in adjustment mapping relations for user.

Illustratively, terminal device 100-2 can store the letter that the mapping relations for generating the first interference signal include The value range of number parameter value.When terminal device 100-2 detects the input operation of user's input, terminal device 100-2 can Stored value range is read, to show adjustment option.Terminal device 100-2 can receive user for adjustment option When input operation, input operation is responded, the signal parameter value in mapping relations is adjusted to take indicated by input operation Value realizes the update to mapping relations.

Terminal device 100-2 if it is determined that when generating the first interference signal based on updated mapping relations, obtain the Preset threshold is still greater than in the volume value of four signals, then terminal device 100-2 can continue to output prompt information, to prompt to use Continue to update mapping relations in family.

In a kind of possible embodiment, the function that terminal device 100-2 can be set for updating mapping relations is opened It closes.When terminal device 100-2 detects that the functional switch is in the open state, then mapping relations are updated；Conversely, not right Mapping relations are updated.Or terminal device 100-2 can be updated periodically mapping relations, or be made by oneself by system Justice updates mapping relations.

Embodiment as above describes terminal device 100-2 and is under relatively quiet environment, how to avoid due to from terminal The third signal of equipment 100-2 leakage leads to the leakage of privacy information.And in practical communication process, user B is set by terminal When standby 100-2 and user A converses, the user around user B still may hear speech signal of the user B to user A, I.e. similar to the first signal.Hereinafter, user B is known as the 5th signal to the speech signal that user A is carried out.

The 5th signal is heard by the other users around user B in order to prevent, leads to the leakage of privacy information, and the application is real The second interference signal for being used for interfering the 5th signal can be generated by sounding component by applying example.Second interference signal and the 5th signal The 6th signal is synthesized in air, so that the amplitude of the 6th signal or intelligibility reduce, avoids privacy information from letting out to reach The purpose of dew.Specifically, the generation method of the second interference signal is similar with the generation method of the first interference signal above, institute Generating the second interference signal with the sounding component of terminal device 100-2 can be with reference to the side for above generating the first interference signal Formula, which is not described herein again.

In some embodiments, when the sound collections element such as microphone of terminal device 100-2 collects five signals, The sounding component of terminal device 100-2 generates the second interference signal, and exports the second interference signal.Wherein, here for generating The sounding component of second interference signal can be the same sounding with the sounding component for above being used to generate the first interference signal Element is also possible to different sounding components.

Embodiment as above describes terminal device 100-2 and is under relatively quiet environment how to avoid letting out for privacy information Dew.And in practical communication process, terminal device 100-2 is likely to be under relatively quiet environment, it is also possible in more noise Miscellaneous environment.If terminal device 100-2 is in more noisy environment, the noise in environment can also be set by terminal The microphone of standby 100-2 collects, and with the 5th signal together as the 5th signal inputted to terminal device 100-1.In this way Cause the noise signal in the 5th signal from terminal device 100-1 of user's A uppick may be larger, reduces user A's Experience.

In consideration of it, terminal device 100-2 in the embodiment of the present application is if it is determined that when more noisy locating current environment, Noise reduction process can be carried out to ambient noise, to reduce the noise of the 5th signal carrying to the greatest extent, reduce the noise of user A uppick A possibility that, promote speech quality.

Specifically, terminal device 100-2 passes through the sound collections elements such as the microphone being arranged thereon, acquisition terminal equipment 5th signal of noise signal and user B input in environment locating for 100-2, and noise reduction process is carried out to noise signal.

In a kind of possible embodiment, the noise reduction that terminal device 100-2 stores the volume for reducing ambient noise is calculated Method, when terminal device 100-1 determines the volume of ambient noise greater than preset threshold, then based on the noise reduction algorithm stored to ring Border noise carries out noise reduction process.Finally just reduce via ambient noise signal in the 5th signal of sounding component output in this way, A possibility that reducing the noise of user A uppick, promotes speech quality.

In conjunction with above-described embodiment and relevant drawings, the embodiment of the present application provides a kind of call method, and this method can be In terminal device (such as mobile phone, tablet computer etc.) with earpiece and microphone and camera and sensor as shown in the figure It realizes.As shown in figure 11, this method may comprise steps of:

Step S111, terminal device detects the first operation for connecting the first user of incoming call.

The terminal device can be above-mentioned terminal device 100-2, and the first user is above-mentioned user A, hereinafter, with this For.

Step S112, the first operation of terminal device response determines what terminal device was presently in when entering talking state Call environment.

Illustratively, when terminal device enters talking state, terminal device can open sound transducer, to determine terminal Noise in equipment local environment.Terminal device can also open the camera being arranged thereon, to determine the current institute of terminal device The call scene at place, such as whether there is other users around elevator or square and terminal device.Alternatively, terminal device The range sensor being arranged thereon can be opened, to determine other users that may be present and terminal device around terminal device Distance.

Step S113, terminal device is if it is determined that be currently at the first call environment, then when receiving second signal, according to First call environment and second signal generate and export the first interference signal.

Step S114, terminal device is if it is determined that be currently at the first call environment, then when collecting five signals, according to First call environment and the 5th signal generate and export the second interference signal.

Here the first call environment can be understood as the call environment for being easy leakage dialog context, for example, terminal is set It is standby to be in quiet scene, and there are other users around the user of currently used terminal device.

First interference signal is reflecting for the environmental parameter for including and signal parameter value based on second signal and call environment It penetrates and closes generation, for reducing the intelligibility of third signal.5th signal can be second user and use the terminal device The signal that user issues.Second interference signal is the environmental parameter for including and signal parameter based on the 5th signal and call environment Generation is closed in the mapping of value, for reducing the intelligibility of the 5th signal.

First interference signal and the second interference signal may each be above-mentioned audio signal, harmonic signal, frequency domain masking letter Number and time domain masking signal etc..Terminal device generates which kind of the first interference signal or the second interference signal actually, can be according to end Current talking environment locating for end equipment determines, to avoid the leakage of privacy information as far as possible.Specifically, generating the with terminal device For one interference signal, terminal device stores the mapping relations for generating the first interference signal, which is environment The corresponding relationship of parameter and signal parameter value, signal parameter value may be considered the value of the property parameters of signal.Terminal device A kind of first interference signal can be generated based on the environmental parameter and mapping relations that determining call environment includes.

Illustratively, terminal device can predefine the opposite position of other users and terminal device around terminal device Relationship is set, with determination target area above-mentioned.Terminal device is preferentially selected from multiple mapping relations of storage based on target area It selects mapping relations corresponding with target area and generates corresponding first interference signal.

Terminal device response the first input operation, second signal is exported if receiving second signal, is generating first The first interference signal is exported when interference signal, exports the second interference signal when generating the second interference signal.

Illustratively, the first sounding component of terminal device setting can export second signal.In terminal device for example After dsp chip generates the first interference signal, the first interference signal can be exported to the second sounding component of terminal device, by Second sounding component exports the first dry signal.Second signal is revealed the third signal to be formed via terminal device and is passed in air It broadcasts, the first interference signal is also propagated in air, and third signal and the first interference signal form fourth signal in communication process. Since the first interference signal is generated based on second signal, i.e. the original signal of the characterization dialog context of the first user input, So the first interference signal is generated based on second signal, is had specific aim, can preferably be reduced the intelligibility of third signal.Example Such as, the first interference signal is that the corresponding phase of the third signal that is leaked with second signal is modulated, signal similar in amplitude.This The intensity of sample third signal and the fourth signal of the first interference signal synthesis is located at around listener with regard to lower so as to reduce Other users uppick fourth signal a possibility that, can not correctly interpret third signal, achieve the purpose that protect privacy information.

Illustratively, the third sounding component of terminal device setting can export the second interference signal.5th signal is in sky It is propagated in gas, the second interference signal is also propagated in air, and the 5th signal and the second three signals of interference couple in communication process. Since the second interference signal can reduce the signal of the intelligibility of the 5th signal, so, the 5th signal and the second interference signal coupling The intelligibility of the signal formed after conjunction is lower, so that a possibility that user for reducing surrounding correctly interprets five signals, reaches Protect the purpose of privacy information.

In another embodiment, this method can also include:

Terminal device periodically determines the call environment that is presently in of terminal device, is used to generate the to be adaptively adjusted The mapping relations of one interference signal or the second interference signal.

In another embodiment, for terminal device when entering talking state, what can be presently in based on terminal device is logical The noise size for talking about environment judges whether to enter noise reduction mode or privacy protection mode.Here noise reduction mode refers to terminal The received acoustic signals of equipment carry out noise reduction process.Privacy protection mode can be the mode for generating the first interference signal, can also To be the mode for generating the second interference signal, for the ease of distinguishing, the mode for generating the first interference signal is hereinafter known as the The mode for generating the second interference signal is known as the second privacy protection mode by one privacy protection mode.

Specifically, referring to Figure 12, step S121, terminal device judges whether to enter noise reduction according to current call environment Mode.

Illustratively, terminal device can detecte the noise in current call environment when entering talking state.If The amplitude of ambient noise signal in the current talking environment is higher than preset threshold, it may be considered that terminal device is in opposite Noisy environment, then it is smaller a possibility that leakage of private information, determine that terminal device does not enter privacy protection mode at this time.This There is no need to open camera, perhaps sensor determines that other kinds of call environment is for example conversed around place or user to sample With the presence or absence of other users, to save the energy consumption of terminal device as far as possible.

But in this case if terminal device is in relatively noisy environment, noise signal and user in environment The voice signal of input is collected by microphone together.In order to reduce the influence for the voice signal that noise inputs user, improve Speech quality needs to carry out noise reduction process to the voice signal of input, at this point, terminal device, which determines, enters noise reduction mode.

When terminal device enters noise reduction mode, when microphone collects the 5th signal and ambient noise signal of input When, ambient noise signal in the noise reduction process received second signal of terminal device last in this way is carried out to ambient noise signal and is just subtracted Less, a possibility that reducing the noise of user's uppick, speech quality is promoted.

Step S122, terminal device determination does not enter noise reduction mode, judges whether to enter privacy protection mode.

Specifically, can recognize if the amplitude of the ambient noise signal in current call environment is lower than preset threshold It is in relatively quiet environment for terminal device, then larger a possibility that leakage of private information.At this point, terminal device determination can To enter privacy protection mode.

Further, terminal device, which is opened, whether there is other users in camera detection call environment.If terminal is set Standby to determine that other users are not present in surrounding, then terminal device determination does not enter privacy protection mode, to practice every conceivable frugality, terminal is set Standby energy consumption.Otherwise, if terminal device determines surrounding there are other users, terminal device can be determined to be protected into privacy Shield mode.

Specifically, if terminal device receives second signal, terminal device, which determines, enters first in step S123 Privacy protection mode.In step S124, if terminal device collects the 5th signal, terminal device determines hidden into second Private protected mode.
