Description

Method and terminal for controlling audio during a call

technical field

The present application relates to the technical field of mobile communication, and in particular to a method and a terminal for controlling audio during a call.

Background technique

In the standby state, the mobile phone usually allows the user to set the scene mode and freely switch between different scene modes. Scene modes include: Standard, Silent, Conference, Outdoor, etc. In different scenarios, you can usually set the ringing method when an incoming call or text message comes, including: ringtone type, ringtone volume, and whether to vibrate, etc. However, the audio during the call cannot be controlled.

In the call state, you can adjust the volume of the mobile phone, so as to enlarge or reduce the volume of the other party. But this is just a simple volume adjustment. If the other party's voice is low or breathy, even if the volume is turned up, the content of the other party's speech may not be heard clearly.

The CDMA system uses advanced spread spectrum technology and digital voice coding technology to reduce the noise of the audio in the mobile phone call. Its vocoder can dynamically adjust the data transmission rate and select different levels of transmission according to the appropriate threshold value. Thus, the noise during the call can be greatly reduced. At the same time, the threshold value can be changed according to the change of the background noise. In this way, even in the case of high background noise, better call quality can be obtained, so that there is almost no noise during the call of the user. Especially when one user is in an environment with noisy background, the other party can clearly hear the user's voice. However, in some scenarios, the user may want the other party to hear the background sound on his side.

Detailed ways

In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and examples.

As mentioned in the background technology, the existing technology lacks an effective technical solution for controlling the audio during a call, and the user may encounter many different scenarios when actually using a mobile phone to make a call, and in different scenarios, may In-call audio needs to be processed differently to meet different functional requirements. For example:

Application Scenario 1: A certain user is in a meeting, and he can only speak very softly when answering the phone, which will cause the other party to be unable to hear clearly. Therefore, it is necessary to process the audio of the user so that the other party can hear the speech clearly What the user said.

Application scenario 2: A user is participating in a concert. The user calls a friend and wants the other party to hear the music being played at the concert. However, since mobile phones generally adopt the processing method of reducing environmental noise, the background noise is shielded. Therefore, it is necessary to process the user's audio so that the other party can hear the music being played.

In order to solve the above technical problems, the present application proposes a method for controlling audio during a call, including:

First, detecting the user's selection of the call mode; here, the call mode may include: a first mode and a second mode;

Then, according to the detected call mode, corresponding processing is performed on the user's audio during the call, so that the processed audio meets the requirements of the call mode.

According to the above analysis of the prior art problems, the application proposes:

The audio requirements of the first mode are: the processed audio retains the ambient noise of the user's environment; hereinafter this mode is called theater mode;

The audio requirement of the second mode is: the processed audio is close to the user's normal voice; hereinafter this mode is called conference mode;

In addition to the above two modes, there may also be a normal mode, that is, the audio is processed according to the prior art.

Specifically, when the detected call mode is theater mode, the modem of the terminal can be adjusted to modulate the audio of the user's call in a way that does not shield the ambient noise, so that the other party can clearly Hear the music on this side. At the same time, the audio during the user's call can be collected by adopting a sound collection method that can keep the ambient noise as much as possible. For example: in normal mode, the frequency range of audio collection may be limited to the frequency range of human speech. In order to keep the environmental noise, the frequency range of audio collection can be appropriately amplified in theater mode to capture the environmental noise.

When the detected call mode is a meeting mode, a preferred processing method is: firstly, perform speech recognition on the audio in the user's call to obtain the content of the audio; then, according to the pre-collected common voice of the user samples, and convert the content of the audio into the corresponding user's normal voice, so that the other party can hear the normal user's voice.

When the detected call mode is a conference mode, another preferred processing method is: according to the pre-collected sample of the user's ordinary voice, complement the audio and the user's voice in the audio waveform of the user's call. Differences in ordinary voices, for example: when the user speaks breathlessly, part of the voice vibration will be missing, and the part of the voice vibration can be supplemented.

In the conference mode, no matter which processing method is adopted, the volume of the processed audio can be increased to achieve the purpose of converting the whispered voice into a normal voice.

If it is detected that the call mode selected by the user is the normal mode, corresponding processing can be performed according to the prior art, that is, ambient noise is shielded, and the voice of the user during the call is truly restored.

In a specific implementation, a menu as shown in Figure 1 can be set in the terminal, that is, a menu for prompting the user to select a call mode, and the call modes available for the user to choose are displayed in the menu, for example, theater mode, conference mode, normal mode. And according to the user's choice, control the opening and closing of the corresponding function. If the user selects the theater mode or conference mode during the use of the terminal, it means that the audio control function corresponding to the call mode is turned on, and the terminal can adopt corresponding processing methods to process the audio during the user call, so that after processing The audio meets the requirements of the corresponding call mode; if the user selects the normal mode during the use of the terminal, it means that there is no need to perform additional processing on the audio during the call, and the terminal does not perform additional operations on the user's audio during the user call.

This application processes the audio in the user's call, which is divided into the following situations:

The first case: if the user's selection of the call mode is detected in the standby state, the audio in all calls of the user will be processed corresponding to the call mode selected by the user. For example: assume that the user sets the call mode when using the terminal at ordinary times. At this time, the user wants to set the default call mode of the terminal. Therefore, after setting, all calls of the user need to be processed according to the call mode selected by the user. In this case, a schematic diagram of an interface of the terminal is shown in FIG. 2 .

The second case: if the user's selection of the call mode is detected when the user makes an outgoing call or receives an incoming call, the audio in the user's current call is processed corresponding to the call mode selected by the user. For example: Suppose the user sees an incoming call, and sets the call mode before answering the incoming call, or during the process of making an outgoing call. At this time, the user wants to use the call selected by the user for the current incoming call or outgoing call that is about to be answered. mode, in this case, the user's call should be handled in a corresponding way. In this case, the schematic diagram of the interface of the terminal is shown in FIG. 3 . On the incoming call interface, a selection button of "call mode" can be added, and the user can click this button to select the call mode.

The third case: if the user's selection of the call mode is detected in the call state, the audio in the current call after the user's selection of the call mode is detected is processed corresponding to the call mode selected by the user. For example: Suppose the user is talking (including: answering incoming calls and making outgoing calls), the user has adjusted the call mode according to the environment at that time, and the user has established a call with the other party at this time, so the audio after this call is required Deal with it accordingly. In this case, the schematic diagram of the interface of the terminal is shown in FIG. 4 . In the call interface, a selection button of "call mode" can be added, and the user can click this button to select the call mode.

In order to realize the above method proposed in this application, it is necessary to make corresponding improvements to the underlying library in the terminal to provide corresponding support. The underlying library is the core module of the function realization part, and is mainly responsible for processing the audio during the user call.

Corresponding to the above method, the present application also discloses a terminal as shown in Figure 5, the terminal at least includes: a detection module and an audio control module, wherein:

The detection module is used to detect the user's selection of the call mode, and the call mode includes: a first mode and a second mode;

The audio control module is used to process the input audio according to the call mode detected by the detection module, so that the output audio after processing meets the requirements of the call mode.

As mentioned above, the first mode may be called theater mode, and the second mode may be called meeting mode.

Since the modem in the terminal usually performs noise reduction processing on the user's voice when recording the voice, corresponding to the theater mode, the modem needs to be adjusted so that the noise reduction process of the modem retains the music being played in the theater. Therefore, corresponding to the theater mode, preferably, the terminal shown in FIG. 5 may further include: a modem;

The audio control module may further include: a modem communication unit;

When the detection module detects that the user selects the theater mode, it notifies the modem communication unit;

The modem communication unit adjusts the modem mode according to the notification of the detection module;

Corresponding to the conference mode, the audio control module in the terminal shown in FIG. 5 may further include: a voice processing unit;

When the detection module detects that the user selects the conference mode, it notifies the voice processing unit;

The voice processing unit performs voice recognition on the input audio according to the notification of the detection module to obtain the content of the audio, and converts the content of the audio according to the sample of the user's ordinary voice collected in advance Convert it to the corresponding user's normal voice, and output the resulting audio.

Corresponding to the conference mode, the audio control module in the terminal shown in FIG. 5 may further include: a voice processing unit;

When the detection module detects that the user selects the conference mode, it notifies the voice processing unit;

The speech processing unit completes the difference between the input audio and the user's ordinary voice in the waveform of the input audio according to the notification of the detection module and according to the sample of the user's ordinary voice collected in advance, will result in the audio output.

Before outputting the obtained audio, the speech processing unit may further increase the volume of the obtained audio.

Preferably, if the detection module detects the user's selection of the call mode in the standby state, the audio control module is notified to perform the corresponding processing on the audio in all calls of the user;

If the detection module detects the user's selection of the call mode when the user dials an outgoing call or answers an incoming call, the audio control module is notified to perform the corresponding processing on the audio in the user's current call;

If the detection module detects the user's selection of the call mode in the call state, the audio control module is notified to perform the corresponding processing on the audio in the current call after the user's selection of the call mode is detected.
