Detailed ways

The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, but not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

1 is a schematic flowchart of a method for adjusting a call volume according to an embodiment of the present invention. As shown in the figure, the method for adjusting a call volume in this embodiment may include the following processes:

S101. During a call, the terminal detects a call environment in which the terminal is located, and acquires a volume range that matches a call environment in which the terminal is located.

Specifically, the terminal includes various mobile communication devices capable of conversation, such as mobile phones, PHS, landline telephones, walkie-talkies, pagers, and wireless telephones, as well as devices capable of network communication, such as personal computers, handheld computers, and various types of devices. Wear the device. The calling environment in which the terminal is located is the calling environment in which the terminal user is currently located, and obtains the volume range that matches the calling environment in which the terminal is located, that is, the volume range is obtained according to the quiet or noisy current environment of the user.

Normally, the volume is measured in decibel (dB), and the human ear feels like decibels as shown in Table 1:

Table 1

分贝值Decibel value	人耳感受Human ear experience
1分贝1 decibel	刚能听到的声音Just heard
15分贝以下Less than 15 decibels	感觉安静Feeling quiet
30分贝30 decibels	耳语的音量大小Whistle volume
40分贝40 decibels	冰箱的嗡嗡声The buzz of the refrigerator
60分贝60 decibels	正常交谈的声音Normal conversation
70分贝70 decibels	相当于走在闹市区Equivalent to walking in downtown
85分贝85 decibels	汽车穿梭的马路上Car shuttle on the road
95分贝95 decibels	摩托车启动声音Motorcycle start sound
100分贝100 decibels	装修电钻的声音Renovating the sound of an electric drill
110分贝110 decibels	卡拉OK、大声播放MP3的声音Karaoke, loudly playing MP3 sound

120分贝120 decibels	飞机起飞时的声音The sound of the plane taking off
150分贝150 decibels	燃放烟花爆竹的声音The sound of fireworks and firecrackers

Optionally, each person's subjective feelings on the volume will be different, some are dull and a bit sensitive. In addition to evaluating the user's hearing according to the general situation, the user's hearing can also be authenticated individually, through the corresponding hardware of the terminal. Or software, test the user's hearing, and obtain the user's corresponding auditory feeling table.

When the user is in a different environment, the volume value of the received call will be different. For example, if the user is currently walking in the market, he will require a higher volume value for the currently received call; and if the user is currently sleeping at night, he will require a lower volume value for the received call; or the user Walking in the mall, the surrounding environment may be noisy for a while, and it is quiet at the moment, so the user's request for the volume value of the call will also change. If the environment changes every time, the user has to adjust the volume of the mobile phone, which will cause great inconvenience and also make the user have a bad calling experience.

Therefore, according to the call environment in which the terminal user is located, the volume range of the terminal can be set, so that the terminal call volume can be better adapted to the user's auditory needs. In an optional embodiment, the calling environment in which the terminal is located can be determined by the number of voiceprints included in the environment. The more the voiceprints, the more noisy the current environment, and the terminal needs to provide a call with a higher volume value to make the user Listen to the call content. Optionally, the calling environment in which the terminal is located can also be determined by the volume of the environment. The greater the volume of the environment, the more noisy the current environment, and the terminal needs to match the call with a higher volume value for the user. These two typical call environment determination methods will be described in detail through Embodiment 2 and Embodiment 3. In addition, the calling environment in which the terminal is located may also be judged by the tone and tone received by the terminal, or may be determined by a keyword in the environment received by the terminal, for example, the terminal receives an indication of volume adjustment, or receives a judgment user. Keywords in real-time scenarios such as class or meeting can determine the calling environment in which the terminal is located, and then match the corresponding volume range for the calling environment.

In addition, the volume range is used as an interval range, including the maximum value and the minimum value. It can also be called the start value and the end point value. For example, the volume range is between 70 decibels and 100 decibels. The maximum value is 100 decibels and the minimum value is 70 decibels. It is also possible to describe 70 decibels as the starting point value and 100 decibels as the end point value. Or by mathematical expressions, the interval range is [70,100], or (70,100), or [70,100), or (70,100], where [70,100] indicates that the endpoint values 70 and 100 are included, and (70,100) indicates that the endpoint is not included. Values 70 and 100, [70, 100) indicate that endpoint 70 is included but endpoint 100 is not included, and (70, 100) indicates that endpoint 70 is not included but endpoint 100 is included.

Optionally, the terminal volume range is set according to the calling environment in which the terminal is located, and the human hearing range needs to be considered. For example, when the volume is less than 20 decibels, the human ear is difficult to hear, and when the volume is greater than 100 decibels, it will be given. The ear brings a lot of damage, so the value is adjusted between 20 decibels and 100 decibels when the volume range matching the calling environment in which the terminal is located is obtained. In addition, the sound frequency, ie the Hertz value, should also be used as a reference parameter for the volume.

After obtaining the volume range that matches the communication environment in which the terminal is located, S102 is performed.

S102. Detect a call volume value of the currently received call audio data.

The call audio data currently received by the terminal, that is, the call audio data currently transmitted by the terminal through the signal, is a frequency and amplitude change information carrier of regular sound waves with voice, music and sound effects.

Audio information can be classified into regular audio and irregular sound according to the characteristics of sound waves in the audio data. The regular audio can be divided into voice, music and sound effects, and the irregular audio is a kind of noise that disturbs the hearing of the human ear. In an optional embodiment, if the volume of the received audio data is directly determined as the current call volume, there is a possibility that the user cannot listen to the set volume value because there is a large amount of noise in the currently received audio data. To valid call audio. Therefore, valid call data and noise data can be extracted from the call audio data currently received by the terminal, and then the volume value of the valid call data therein is determined as the current call volume value. In an alternative embodiment, the noise in the received audio data may also be removed, and only the valid call data is retained, and then the volume value of the valid call data is used as the current call volume value.

After detecting the current call volume value, S103 is performed.

S103. Check whether the voice volume value is within a range of a volume that matches a call environment in which the terminal is located.

The volume range matching the call environment in which the terminal is located refers to the terminal call environment detected in S101, and the set volume range matched with the terminal call environment. Being within the volume range means that the detected volume value is not less than the minimum value of the range and is not greater than the maximum value of the range.

In an optional embodiment, for example, it is detected that the volume in the current call environment is 20 decibels, and the terminal setting matches the volume range of 25 decibels to 35 decibels, which prevents the received volume from being too small and is covered by the ambient volume. At the same time, to prevent the received volume from being too large, causing a hearing burden to the user. Detect the volume value received by the terminal and determine if it is between 25 decibels and 35 decibels.

S104. Maintain the current call volume value.

Specifically, it is compared whether the call volume value is within the volume range that matches the call environment in which the terminal is located, and if so, the current call volume value is kept unchanged.

In an optional embodiment, as in the case described in S103, it is detected that the volume in the current call environment is 20 decibels, and the volume range matched by the terminal is 25 decibels to 35 decibels, and the current call volume value is 27 Decibel, within 25 decibels to 35 decibels, keeps the current call volume value constant.

S105. Adjust the current volume value to a volume range that matches the communication environment in which the terminal is located.

Specifically, the comparison call volume value is within a volume range that matches the communication environment in which the terminal is located, and if not, the current volume value is adjusted to be within a volume range that matches the communication environment in which the terminal is located.

In an optional embodiment, as in the case described in S103, it is detected that the volume in the current call environment is 20 decibels, and the volume range matched by the terminal is 25 decibels to 35 decibels, and the current call volume value is 20 decibels. Decibel, not within 25 decibels to 35 decibels, need to adjust the current volume value between 25 decibels and 35 decibels. Optionally, the current volume can be adjusted to a minimum satisfaction value, which is 25 decibels in this embodiment; the current volume can also be adjusted to a maximum satisfaction value, which is 35 decibels in this embodiment; the current volume can also be The minimum value adjustment can reach the preset range. In this embodiment, the current call volume value is 20 decibels, and the minimum adjustment range is increased by 5 decibels to 25 decibels; the current volume value can also be adjusted to the middle value of the preset range, because the intermediate value is generally used as an average value. Meet the needs of all types of hearing users. In an optional embodiment, the current volume value may also be adjusted to other optimal values within a preset range according to the user's personal situation.

In this embodiment, by acquiring the current call environment, setting a volume range that matches the current call environment; detecting the currently received call volume value, extracting valid call data and noise data therein, and determining the current call volume according to the valid call data. Value; finally compare whether the current call volume value is within the set volume range, and if not, adjust the current call volume value to the volume range. The process automatically detects the current call to the most appropriate volume value by detecting the environment in which the terminal user is located and simultaneously detecting the noise situation at the sound source. The volume instability during the manual adjustment of the voice volume value is reduced, the user's multiple volume adjustment operations are avoided, and the call information reception rate is improved.

FIG. 2 is a schematic diagram of a process for obtaining a volume range according to an embodiment of the present invention. As shown in the figure, the method for obtaining a volume range in the embodiment may include the following processes:

S201. Acquire audio data of a call environment in which the terminal is currently located.

Specifically, the digitized sound data is audio data. The audio data is displayed by an electrical instrument, and a waveform and a spectrogram of the sound can be obtained.

The sound in the environment is very complicated, but at the same time it has certain rules. For example, the noise is generally irregular audio, and the sound of the human voice and the sound of the instrument are generally regular spectrum. After obtaining the audio data in the environment, the display can be performed by an electrical instrument, and different wavelengths, frequencies, intensities, and rhythms of different sounds can be obtained, and the audio features are analyzed, and valid data is obtained therefrom to determine the current call environment.

S202. Determine, according to the audio data, a quantity of voiceprints included in a call environment in which the terminal is currently located.

Specifically, according to the acquired audio data of the call environment, the sound wave corresponding to the audio data can be obtained, and the language map converts the change of the sound wave into the intensity, the wavelength, the frequency, and the rhythm of the electrical signal, and the instrument draws the changes of the electrical signals. The spectrum of the spectrum becomes a voiceprint.

Modern scientific research shows that human voiceprints have the characteristics of specificity and relative stability. Through the voiceprint map, different voiceprint information of different people can be extracted, and accordingly, the number of voiceprints contained therein can be distinguished. In general, the more the number of voiceprints included in the environment, the more people are currently speaking, the more noisy the current environment is; correspondingly, if the number of voiceprints contained in the current environment is less, the less people are currently speaking. , then the quieter the current environment.

After determining the number of voiceprints included in the call environment in which the terminal is currently located, S203 is performed.

S203. Acquire, according to a preset correspondence between the number of voiceprints and the volume range, a volume range corresponding to the number of voiceprints currently included in the call environment as a volume range that matches the call environment of the terminal.

In an optional embodiment, the correspondence between the number of voiceprints and the volume range is a selectable correspondence, that is, the terminal may match the number of voiceprints and the volume range according to a normal situation, or may be a user. Match the number of voiceprints and the volume range according to your personal situation.

Optionally, if it is detected that the number of voiceprints included in the calling environment of the terminal is 2, it can be inferred that someone in the current environment is in a conversation, and the current environment volume is determined to be about 50 decibels, and the volume range matching the current environment is determined. It can be set to 50 decibels to 65 decibels, that is, when the volume of the call received is between 50 decibels and 65 decibels, the user can make a normal call.

In an alternative embodiment, the correspondence between the number of voiceprints and the volume range can be set as follows:

Table 2

声纹数量(个)Number of voiceprints	对应音量范围(分贝)Corresponding volume range (decibel)
00	[25,40)[25,40)
11	[40,50)[40,50)
2～32 to 3	[50,65)[50,65)
4～54~5	[65,80)[65,80)
>6>6	[80,90)[80,90)

When the terminal receives the call, it detects the number of voiceprints in the current environment and acquires a volume range corresponding to the number of voiceprints.

In this embodiment, the correspondence between the number of voiceprints and the volume range is preset, and then the number of voiceprints in the call environment is detected, and the volume range corresponding to the number of voiceprints in the call environment is obtained as the volume matching the terminal call environment. range. In this process, the call environment in which the terminal is located is quantized by the number of voiceprints, and the volume range is matched according to the number of voiceprints, thereby improving the matching accuracy of the call environment and the volume range.

FIG. 3 is a schematic flowchart of another method for obtaining a volume range according to an embodiment of the present invention. As shown in the figure, the method for obtaining a volume range in the embodiment may include the following processes:

S301. Acquire audio data of a call environment in which the terminal is currently located.

Specifically, the audio data of the call environment in which the terminal is currently located is the same as the process in S201, and details are not described herein again.

S302. Determine, according to the audio data, an ambient volume of a call environment in which the terminal is currently located.

Specifically, according to the acquired audio data of the call environment, a waveform diagram of the corresponding audio data may be obtained, where the waveform diagram includes amplitude information, that is, a distance of the particle from the equilibrium position, reflecting a pressure change from the waveform peak to the trough, and the wave carrying How much energy. The sound of the high amplitude waveform is large; the sound of the low amplitude waveform is quieter.

After determining the ambient volume level according to the waveform diagram, S303 is performed.

S303. Acquire a volume range corresponding to an environment volume level of the current call environment according to a preset relationship between the preset volume level and the volume range, and use the volume range that matches the call environment of the terminal.

In an optional embodiment, the correspondence between the ambient volume and the volume range is a selectable correspondence, that is, the ambient volume and the volume range may be the same, or may have a certain difference, and the difference may be according to a normal situation. Uniform settings can also be made individually depending on the individual's personal circumstances. When the volume in the environment is large, the user's listening to the call sound will be greatly affected. If the call sound is to be distinguished from the scene affected by the ambient volume, then The volume of the voice can be the same as the volume of the environment, because the call terminal can be placed close to the human ear, so the user can distinguish the call volume in the same decibel size. Optionally, the call volume can be greater than the ambient volume, which makes it easier for the user to distinguish the call sound from various types of sounds. In addition, in a noisy environment, the minimum value of the call volume is set to be greater than the ambient volume, so that the user can distinguish the call tone from various types of sounds. At the same time, in a quiet environment, it is necessary to set the maximum value of the call volume to be less than a certain threshold, thereby preventing the user from Receiving louder voices in a quiet environment causes hearing discomfort.

In an alternative embodiment, the correspondence between the volume of the environment and the volume range can be set as follows:

table 3

环境音量n(分贝)Ambient volume n (decibel)	对应音量范围(分贝)Corresponding volume range (decibel)
n<20n<20	[25,40)[25,40)
20<n<6020<n<60	[n+5,65)[n+5,65)
60<n<7060<n<70	[n+10,85)[n+10,85)
n>70n>70	[85,90)[85,90)

After detecting the current call environment of the terminal, the volume range corresponding to the ambient volume of the current call environment is obtained as the volume range matched with the terminal call environment according to the corresponding relationship.

In the embodiment of the present invention, the correspondence between the volume of the environment and the volume range is set; by detecting the audio data of the current environment of the terminal, determining the volume of the environment in which the terminal is currently located; and obtaining the current call. The volume range corresponding to the ambient volume level of the environment serves as a volume range that matches the call environment of the terminal. In this process, the terminal call environment is quantized into the environment volume of the call environment in which the terminal is located, and then the volume range corresponding thereto is set according to the size of the environment volume, and finally the volume range matched with the current environment volume is obtained according to the detected current environment volume. Improves the matching accuracy of the ambient volume and volume range.

In an optional embodiment, the volume range that matches the call environment in which the terminal is located may also be considered to join the contact information, and the noise may be processed when the current call volume value is obtained. As shown in FIG. 4, FIG. 4 is a schematic flowchart of another method for adjusting the volume of a call in the embodiment of the present invention. As shown in the figure, the method for adjusting the volume of a call may include the following processes:

S401: During a call in the terminal, detecting a call environment in which the terminal is located.

Optionally, the call made by the terminal may be a telecommunication mobile phone call, or an IP phone call, or a data network call, or a walkie-talkie call or a pager call. The call environment in which the terminal is located, that is, the call environment in which the terminal user is located, may include volume information, voiceprint quantity, tone color information, or keyword information in the environment. In an optional embodiment, if the terminal includes a camera, when detecting the communication environment in which the terminal is located, it is also possible to detect picture information in the environment, including weather, time, face or scene information, and the like.

S402. Obtain contact information of the current call.

Specifically, during the process of the call, the individual may include some specific habits, obtain the contact information of the current call, and set the call volume range to the contact in a targeted manner.

In an optional embodiment, the information of the current call contact may include the contact's name, nickname or ID number, and also includes the contact's gender, age or common call volume. Some contacts have a softer voice during the call, so the terminal needs to set a higher volume range start value for him; similarly, if the contact sound is high, the terminal needs to set a lower volume range end point for him. Value; in addition, if it is a more important contact, such as a parent, child, teacher, boss or important customer, the user pays more attention to the content of the call with such people, so it needs a higher call volume, then the setting of the call range is also It will be different. As shown in Figure 5, (a) is a contact classification, the end user classifies the contacts as "important" and "regular", the important category contains 5 contacts, and the general category contains 30 contacts; (b) For the volume range corresponding to the contact category, the five contacts in the important category are “A1”, “B2”, “C3”, “Ding 4”, “Ping 5”, and the user sets them. The corresponding volume range is 50 decibels to 90 decibels. If you need to change the contact classification information or the corresponding volume range information, select the “Edit” in the list to modify the current settings. After obtaining the contact information of the current call, execute S403.

S403. Acquire, according to the contact information and a call environment in which the terminal is located, a volume range that matches a call environment in which the terminal is located.

Specifically, in combination with the contact information and the call environment in which the terminal is located, a volume range that satisfies both of the conditions is obtained. In an optional embodiment, the calling environment of the terminal is determined by the number of voiceprints included in the call environment and the volume of the environment volume, and the number of voiceprints is detected to be 2, and the volume of the environment is 50 decibels; The call contact belongs to the category of "important" in Figure 5, then the volume range of the contact is 50 decibels to 90 decibels; according to these three conditions, the intersection of them is obtained, and referring to Table 2, the number of voiceprints is 2 The volume range is 50 decibels to 65 decibels. Referring to Table 3, when the ambient volume is 50, the corresponding volume range is 55 decibels to 65 decibels. Therefore, the intersection can be seen to match the current call environment with a volume range of 55 decibels to 65 decibels.

Optionally, if the common intersection of the three factors does not exist, the call range is determined according to the intersection of the two factors, and if there are two disjoint intersections, the user is prompted to select one of the call ranges. In an optional embodiment, the user may also set the reference priority of the two information of the call environment and the call contact in advance, so when the call range of the two does not have an intersection, the call corresponding to the higher priority factor is selected. The range is the call range of the current terminal.

S404. Extract valid call data and noise data from the currently received call audio data.

The valid call data refers to the regular sound data of the person in the call audio data, and the noise data is an irregular data of a group of call voices that do not belong to the person. In an alternative embodiment, the noise data includes ambient noise during the call audio data pickup process, device noise during transmission, or hardware failure during playback. To extract valid call data and noise data, the noise data can be directly removed to retain only valid call data, or the valid call data and the noise data can be separated. Methods that can be employed include low pass filtering, band pass filtering and high pass filtering, Kalman filtering, and wavelet denoising. After the valid call data and the noise data are extracted from the currently received call audio data, S405 is performed.
