Specific embodiment
Refering to fig. 1, Fig. 1 is the flow chart of one embodiment of voice response method of the present invention, and method includes:
Step S101: it detects from extraneous call voice;
Mobile device passes through voice pick device, such as microphone, the call voice in the real-time detection external world.
Step S102: when the size of extraneous call voice is more than the preset voice ginseng for starting voice response function When examining value, the call speech samples for existing with calling voice to match are searched whether;
Phonetic reference value can be indicated by the size of current or voltage, naturally it is also possible to be otherwise.Extraneous Whether the size for calling voice is more than preset for starting the phonetic reference value of voice response function, can be by comparing extraneous The corresponding measurement electric current that is converted to of call voice or measurement voltage, with preset for starting voice response function Current or voltage carries out.Such as when the extraneous corresponding measurement voltage of call voice is more than preset for starting call voice function When the voltage of energy, then start voice response function, searches whether the call speech samples for existing with calling voice to match;When outer When the corresponding measurement electric current of the call voice on boundary is more than the preset electric current for being used to start call phonetic function, then starts voice and ring Function is answered, searches whether the call speech samples for existing with calling voice to match.It is logical with phonetic reference value in following embodiments For overvoltage expression.
After starting voice response function, it can continue by starting sound-recording function or otherwise to obtain extraneous call Voice will call voice to be converted to the call voice signal that mobile device can identify;It can will specifically continue to obtain outer The call voice on boundary is converted to measurement voltage, and then is converted to the vocative message that mobile device can identify for voltage is measured Number.
It is usually the call voice for searching whether to exist with call the phonetic feature of voice signal to match when being matched Sample.It is mentioned here match refer to call voice signal phonetic feature similarity reach preset similarity or with On, preset similarity needs to be configured according to user, such as 85% or 75% etc., and the present invention is without limitation.When depositing In the call speech samples to match with call voice, step S103 is carried out, otherwise, return step S101 continues to test the external world Call voice.
In actual application, it is possible to voice response function could be started when appearance propagandaing directed to communicate to half, that is, May can only get the other half remaining call voice after starting voice response function, at this moment then only obtain it is remaining this A part calls voice and is converted, matched.Here conversion includes that the call voice that will acquire is converted to measurement voltage, into And measurement voltage is converted into two steps of call voice signal that mobile device can identify.Extraneous call voice is corresponding Measurement voltage be converted to the call voice signal that mobile device can identify after, looked for whether and exhaled in mobile device Call out the call speech samples that the phonetic feature of voice signal matches.
On the other hand, it is also possible to the last the case where could starting voice response function for calling voice is appeared in, due to The call voice of subsequent acquisition is possible to not matched very little, at this moment can also pass through other side without response Formula, analogy setting starting alarm etc., prompts user to issue again and calls voice.
Step S103: it executes the response corresponding with speech samples are called prestored and operates;
When exist with call voice match call speech samples when, execute prestore with call speech samples it is corresponding Response operation.The response operation done, which can be, to play the voice responsive corresponding with speech samples are called prestored or executes and exhale Speech samples are called out to act accordingly.
For example the call speech samples prestored are " dear ", the response operation corresponding with speech samples are called prestored is Play the voice of " I here ".Then when extraneous voice is " dear ", mobile device plays the voice of " I here ".It moves The owner of dynamic equipment can find the mobile device of oneself quickly.The call speech samples for another example prestored are " to dial ××× Phone ", corresponding response operation is the phone of automatic dialing ×××.When extraneous voice be " phone for dialing ××× ", Then execute the movement for dialing the phone of ×××.
It is appreciated that embodiment of the present invention by making mobile device detection from extraneous call voice first is that started Subsequent phonetic feature matches process, so make that mobile device prestored with call that speech samples are corresponding to respond operation, Rather than in such a way that key in the prior art triggers, make mobile device using more humane, be more convenient, be easier to use;Two It is by incuding extraneous voice power variation, only when extraneous voice size reaches preset for starting voice response function Just control wakes up voice response function when phonetic reference value, realizes dynamic response, avoids long-time from opening voice response function and makes At electric quantity loss, keep the power consumption of mobile device lower.
In addition, the response mode diversification that mobile device response user calls, brings more enjoyment to user's life.
Referring to Fig. 2, another embodiment of voice response method of the present invention includes:
Step S201: setting calls speech samples and response corresponding with speech samples are called to operate and save;
Call speech samples and response operation corresponding with speech samples are called are set in mobile device end and are stored in In mobile device;
Step S202: it is arranged for starting the phonetic reference value of voice response function and saving;
One is preset for starting the phonetic reference value of voice response function, here using voltage as phonetic reference value For.Assuming that voltage is 350mV when people propagandas directed to communicate, then the voltage for starting voice response function can be set being 350mV, it is of course also possible to according to the setting of the demand of user oneself for starting the voltage of voice response function, for example be arranged low In the voltage that the voltage of 350mV or slightly above 350mV are for starting voice response function.In actual application, such as When fruit mobile device system itself has existed the voltage for being used to start voice response function of default, then do not need to be used again In the setting steps of the voltage of starting voice response function, directly with mobile device system default for starting voice response function The voltage of energy is as the voltage for starting voice response function;
It is worth noting that the sequencing of above-mentioned steps S201 and step S202 can be exchanged, that is to say, that also Can first be arranged the phonetic reference value for starting voice response function and save after, then be arranged call speech samples and with exhale The corresponding response of speech samples is called out to operate and save;
Step S203: it detects from extraneous call voice;
Step S204: when extraneous call voice size is more than preset for starting the phonetic reference of voice response function When value, the call speech samples for existing with calling voice to match are searched whether;
Step S205: it executes the response corresponding with speech samples are called prestored and operates;
Aforesaid way, by advance inside mobile device setting call speech samples and with call speech samples it is corresponding Response operation, user can be configured these parameters according to personal preference, so that the realization of voice response more individual character Change, while response mode also becomes more flexible changeable according to the personal settings of user, gives user richer experience.
Wherein, in another embodiment, setting calls speech samples and response corresponding with speech samples are called to grasp Make and the specific steps that save be referring to Fig. 3, as shown, include following sub-step:
Sub-step S301: the instruction recorded and call speech samples is received;
Mobile device receives the instruction that speech samples are called in the recording generated from user's operation;
Sub-step S302: one section of external sound is recorded as call speech samples;
After mobile device receives the instruction that speech samples are called in recording, one section of external sound is recorded as call according to instruction Speech samples.Calling speech samples to can be user is the address that oneself mobile device takes, and is also possible to other voice.Such as it is right The microphone of mobile device give a call " dear " or " love machine " etc. as speech samples are called, be also possible to against movement The microphone of equipment gives a call action command, such as " phone for dialing ××× " etc., and the present invention is not to calling voice herein The concrete form and content of sample are limited;
Sub-step S303: the prompt of output setting response operation corresponding with speech samples are called;
After the completion of calling speech samples to record, mobile device output setting response corresponding with speech samples are called is operated Prompt;
Sub-step S304: the response operation setting corresponding with speech samples are called inputted according to prompt is received;
It is inputted according to sub-step S303 output the prompt for responding operation corresponding with speech samples are called is arranged Operation, mobile device receive the response operation setting corresponding with speech samples are called of input, and response operation is called with corresponding Speech samples are corresponding, for example, call speech samples be " dear " perhaps " love machine " response operation can be set to " " or The sound of the response of " I here ", it is of course also possible to which the sound of some flighty sound or one section of music as response is arranged Sound;If calling speech samples is action command as " phone for dialing ××× ", response operation can be set to execute and dial Make a call ××× etc. corresponding response action;
Sub-step S305: it saves and calls speech samples and response operation setting corresponding with speech samples are called;
The call speech samples recorded and response operation setting corresponding with speech samples are called are saved to movement Equipment completes setting.
It is noted that above-mentioned setting up procedure is a kind of embodiment of setting up procedure of the invention, in practical application In, recording call voice sample operations and progress response operation setting corresponding with speech samples are called, strictly differentiation is successive Sequentially, that is to say, that after receiving the instruction (i.e. above-mentioned sub-step S301) for recording call speech samples, can also first carry out Response operation setting carries out that speech samples is called to record again.Moreover, being also not necessarily intended to that speech samples is called to record completion and ring It answers operation setting to be saved again after the completion, can be retained separately, i.e., call speech samples, which are recorded, completes and carry out again after saving Response operation setting simultaneously saves, or first carries out the recording and the guarantor that carry out calling speech samples after response operation setting saves again It deposits.
Referring to Fig. 4, being the concrete application flow chart of one embodiment of voice response method of the present invention, voice of the invention Response method on mobile phone application include:
Step S401: extraneous sound is received;
Mobile phone constantly receives extraneous sound by microphone.
Certainly, before this, system setting first can be carried out to mobile phone.First in the setting menu of mobile phone, setting is opened Speech samples and response operation setting corresponding with speech samples are called are called in the voltage of dynamic voice response function and setting And it is stored on mobile phone, while the similarity of voice match can also be configured and be saved.Certainly, in actual application In, if limited the voltage of starting voice response function inside cell phone system, do not need to reset voltage, directly The voltage started using the voltage of system default as voice response function.
Step S402: sound is handled;
External sound can be converted to the corresponding measurement voltage of external sound or measurement electric current after mobile microphone.
The corresponding measurement voltage of external sound is sent to voltage comparator to be compared.
Step S403: voltage comparison is carried out;
Measurement voltage after mobile phone will be converted by internal voltage comparator by external sound is used for pre-set The voltage for starting the voltage of voice response function or the starting voice response function of system default is compared.If measuring voltage More than preset for starting the voltage of voice response function starting voice response function, S404 is thened follow the steps, if measurement Voltage is not above the preset voltage for starting voice response function for starting voice response function, thens follow the steps S406;
Step S404: starting voice response function carries out voice match;
When measuring voltage more than the preset voltage for being used to start voice response function, start voice response function, after Continued access receives external sound and is converted to the voice signal that mobile phone can identify, the language to match with voice signal is found in mobile phone Sound sample.After starting voice response function, progress voltage can be stopped and compared to save electricity;
Step S405: if finding the speech samples that similarity reaches 85% or more, sound corresponding with speech samples is executed It should operate, otherwise, not execute response operation;
Step S406: operation is not executed;
When measurement voltage is not above the preset voltage for being used to start voice response function, operation is not executed, such as Mobile phone keeps standby mode if being in standby originally, and continues to external sound.
In the above manner, making mobile device not need key triggering realizes voice response, make the use of mobile device It is more humane, be more convenient, be easier to use.For example, user, which can preset " dear " be used as, calls speech samples, corresponding sound It should reply as " dear, I herein ".When someone calls out " dear ", mobile device will reply that " dear, I am at this In ", it is very humanized;Especially in daily life, Home Alone, often forgets which the phone of oneself puts, and does not have Other mobile phone can dial the phone of oneself, and at this moment, as long as barking out preset call voice, phone will start language automatically Sound equipment is answered, and is done a corresponding response or is played one section of preset response music, user can be made to quickly find the phone of oneself; In another example " phoning Zhang San " can be set as speech samples are called in mobile phone user, corresponding response is set as directly dialling Zhang San is made a call, as long as user cries out " phoning Zhang San " against oneself mobile phone, the phone of mobile phone just automatic dialing Zhang San, Very convenient, the user that does not especially see keyboard to those or will not be made a phone call with cell phone address book provides convenience.
Referring to Fig. 5, the functional block diagram of one embodiment of mobile device of the present invention, mobile device include detection module 51, Searching module 52 and respond module 53, in which:
Detection module 51 is used to detect from extraneous call voice;
Extraneous call voice is constantly detected by detection module 51.
Searching module 52 is used to when extraneous call voice size be more than preset for starting the language of voice response function When sound reference value, the call speech samples for existing with calling voice to match are searched whether;
When extraneous call voice size is more than the preset phonetic reference value for being used to start voice response function, pass through Searching module 52 searches whether the call speech samples for existing with calling voice to match, and query result is exported and gives response mould Block 53.
The phonetic reference value for starting voice response function here preset at is pre-set for starting voice sound Answer the reference value of function, reference value can be with being that voltage or electric current indicate.When extraneous call voice size is more than preset use When starting the phonetic reference value of voice response function, then starts voice response function, search whether to deposit by searching for module 52 In the call speech samples to match with call voice.
Respond module 53 is used to hold when searching module 52 finds the call speech samples to match with call speech samples Response corresponding with the call speech samples operation that row prestores.
