S110. Receive a recording instruction, record according to the recording instruction, and acquire an audio signal during the recording process;

In the embodiment of the present application, the electronic device may be any electronic device such as a mobile terminal, a tablet computer, a PDA (Personal Digital Assistant), a POS (Point of Sales), an in-vehicle computer, a wearable device, and the like.

In one embodiment, the recording instruction may be to click the icon of the recording application on the display interface of the electronic device. For example, when an operation of clicking the screen is received in the icon area of the recording application, the electronic device obtains an instruction to enter the recording function by default, and displays the application interface of the recording program on the display interface. The recording instruction may also be operation information of sliding and/or touching on the screen of the electronic device, for example, on the display interface, the recording application is opened by sliding a circle on the interface. The instruction to enter the recording function may also be preset shortcut key information. For example, when the volume button is pressed long, the recording application program is entered to start the recording function. The instruction to enter the recording function may also be voice control information, etc. For example, when the microphone receives voice information such as "start recording" or "turn on the recorder", it enters the recording function.

It should be noted that the above is only an example of the recording instruction, and the specific form of the recording instruction is not limited in this embodiment, as long as the electronic device can enter the recording function.

After the electronic device receives the recording instruction, it enters the recording function and acquires the audio signal during the recording process.

S120: Obtain the recording mode of the electronic device, where the recording mode includes a screen recording mode and a non-screen recording mode;

After entering the recording function, the electronic device obtains the current recording mode of the electronic device, specifically, identifies whether the electronic device is currently in the screen recording mode. If the received recording command is a screen recording command, the electronic device is currently in the screen recording mode; if the received recording command is a normal recording command, that is, a recording command in a non-screen recording mode, the electronic device is currently in a non-screen recording mode .

Screen recording (SR) technology is usually used to record and save the content displayed on the screen interface for a period of time, for example, the user's operation process on the screen interface or the video content played on the screen interface, etc. Record and save.

S130. Switch an audio processing mode according to the recording mode, the audio processing mode includes a voiceprint processing mode and a sound source processing mode;

In the embodiment of the present application, after acquiring the current recording mode of the electronic device, the corresponding audio processing mode is switched according to the recording mode, and the audio signal acquired during the recording process is processed according to the switched audio processing mode to Get the recording signal.

Specifically, when the acquired recording mode is a non-screen recording mode, the audio signal processing mode is switched to a voiceprint processing mode; when the acquired recording mode is a screen recording mode, the audio signal processing mode is switched To sound source processing mode.

S140. Process the audio signal according to the audio processing mode to obtain a recording signal;

S210. Analyze the voiceprint feature of the audio signal to obtain the voiceprint feature of the audio signal;

Voiceprint (Voiceprint) is the sound wave spectrum carrying verbal information displayed by electroacoustic instruments. The generation of human language is a complex physiological and physical process between the human language center and the pronunciation organs. The vocal organs used by everyone in speech: the tongue, teeth, throat, lungs, and nasal cavity vary greatly in size and shape, so The sound wave spectrum of any two people is different.

Voiceprint features are acoustic features related to the anatomical structure of human pronunciation mechanisms, such as frequency spectrum, cepstrum, formants, pitch, reflection coefficient, nasal sounds, deep breath sounds, hoarse sounds, laughter, etc. Since each person's pronunciation organs are different, the audio signals corresponding to different speakers can be accurately identified by identifying the voiceprint features of the audio signal. Therefore, by identifying the voice of the target object through the voiceprint feature, it is possible to record only the voice of the specific target object.

S220. Match the voiceprint feature of the audio signal with the voiceprint feature in the voiceprint feature model library.

In one embodiment, before matching the voiceprint feature of the audio signal with the voiceprint feature in the voiceprint feature model library, the method further includes establishing a voiceprint feature model library. Specifically, the voice samples of the target object are pre-recorded, and the voiceprint features of each sample are extracted to establish a voiceprint feature model library. Match the acquired voiceprint features of the audio signal with the voiceprint features stored in the voiceprint feature model library. If the matching is successful, the audio signal corresponding to the voiceprint feature is saved as a recording signal; if the matching is not successful, the audio signal corresponding to the voiceprint feature is discarded.

For example, the voiceprint features of user A, user B, and user C are stored in the voiceprint feature model library. When matching the voiceprint features, the acquired voiceprint features of the audio signal (for example, user A's voiceprint features) are matched with the voiceprint features stored in the voiceprint feature model library. Since the voiceprint feature model library contains the voiceprint feature of user A, if the match is successful and it is determined that user A belongs to the target object, the audio signal corresponding to the voiceprint feature of user A is saved as a recording signal; if the acquired audio signal has The voiceprint feature is user D. During the matching process, since there is no voiceprint feature of user D in the voiceprint feature model library, the matching fails, and the audio signal corresponding to the voiceprint feature of user D is discarded.

Further, the parameters of the voiceprint feature mainly include parameters such as volume, tone, and timbre. Therefore, when determining whether the multiple voiceprint features of the acquired audio signal match the voiceprint features stored in the voiceprint feature model library, the electronic device may make a determination based on the above-mentioned several parameters. The following describes the determination method in detail.

For example, when using the tone and timbre to match the voiceprint feature, only the tone and timbre of a certain voiceprint feature of the audio signal and the tone and timbre of the voiceprint feature in the feature model library are matched to determine whether the voiceprint feature is It is consistent with the voiceprint feature in the feature model library. If yes, it means that the voiceprint feature belongs to the target object's voiceprint feature, then the audio signal corresponding to the voiceprint feature is saved as a recording signal; if not, it means that the voiceprint feature does not belong to the target object's voiceprint feature, Then, the audio signal corresponding to the voiceprint feature is discarded.

Specifically, the tone indicates the level of the sound (treble, bass), determined by "frequency", the higher the frequency the higher the tone, the lower the frequency the lower the tone. Each user has its own unique tone. The timbre, also known as timbre, has different characteristics due to the characteristics of different object materials, and everyone's timbre is also different. Because each person's voiceprint features have their own characteristics, the audio signal can be accurately filtered using tones and timbre, which can improve the recording quality.
