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

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.

And after receiving the recording instruction, the electronic equipment enters a recording function and acquires an audio signal in the recording process.

after entering the recording function, the electronic device obtains a current recording mode of the electronic device, and specifically, identifies whether the electronic device is currently in a screen recording mode. If the received recording instruction is a screen recording instruction, the electronic equipment is currently in a screen recording mode; if the received recording instruction is a common recording instruction, namely a recording instruction in a non-screen recording mode, the electronic equipment is currently in the non-screen recording mode.

Screen Recording (SR) technology is generally used to Record and save content displayed on a Screen interface for a certain period of time, for example, Record and save the operation process of a user on the Screen interface or video content played on the Screen interface.

S130, switching audio processing modes according to the recording mode, wherein the audio processing modes comprise a voiceprint processing mode and a sound source processing mode;

in the embodiment of the application, after the current recording mode of the electronic equipment is obtained, the corresponding audio processing mode can be switched according to the recording mode, and the audio signals obtained in the recording process are processed according to the switched audio processing mode to obtain the recording signals.

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

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

in an embodiment, as shown in fig. 2, when the recording mode is the non-screen recording mode, the audio signal is filtered according to the switched voiceprint processing mode to obtain the recording signal, which specifically includes:

s210, analyzing the voiceprint characteristics of the audio signal to obtain the voiceprint characteristics of the audio signal;

voiceprint (Voiceprint), a spectrum of sound waves carrying verbal information displayed by an electroacoustical instrument. The generation of human language is a complex physiological and physical process between human language center and pronunciation organs, and the pronunciation organs used by each person when speaking: the tongue, teeth, larynx, lung, and nasal cavity vary greatly in size and morphology, so the acoustic spectrum varies between any two people.

Voiceprint features are acoustic features related to the anatomy of the human pronunciation mechanism, such as spectrum, cepstrum, formants, fundamental tones, reflection coefficients, nasal sounds, profound breath sounds, humble, laughter, etc. Because the pronunciation organs of each person are different, the audio signals corresponding to different speakers can be accurately identified by identifying the voiceprint characteristics of the audio signals. Therefore, the voice of the target object is identified through the voiceprint characteristics, and recording of only the voice of the specific target object can be achieved.

S220, matching the voiceprint characteristics of the audio signal with the voiceprint characteristics in the voiceprint characteristic model library.

In one embodiment, before matching the voiceprint features of the audio signal with the voiceprint features in the voiceprint feature model library, establishing the voiceprint feature model library. Specifically, sound samples of the target object are input in advance, and voiceprint features of each sample are extracted to establish a voiceprint feature model library. And matching the acquired voiceprint characteristics of the audio signal with the voiceprint characteristics stored in the voiceprint characteristic model library. If the matching is successful, storing the audio signal corresponding to the voiceprint characteristic as a recording signal; and if the matching is unsuccessful, discarding the audio signal corresponding to the voiceprint feature.

For example, stored in the voiceprint feature model library are voiceprint features of the user a, the user B, and the user C. When the voiceprint features are matched, the obtained voiceprint features of the audio signal (for example, the voiceprint features of the user A) are matched with the voiceprint features stored in the voiceprint feature model library. The voiceprint characteristics of the user A exist in the voiceprint characteristic model library, so that the user A is successfully matched and judged to belong to the target object, and the audio signal corresponding to the voiceprint characteristics of the user A is stored as a recording signal; if the voiceprint feature of the acquired audio signal is the user D, in the matching process, the voiceprint feature of the user D does not exist in the voiceprint feature model library, so that the matching fails, and the audio signal corresponding to the voiceprint feature of the user D is discarded.

Furthermore, the parameters of the voiceprint features mainly include parameters of volume, tone, timbre and the like. Therefore, when determining whether or not a plurality of voiceprint features of an acquired audio signal match voiceprint features stored in a voiceprint feature model library, the electronic device may perform the determination based on the above parameters. The following describes the determination method.

For example, when matching the voiceprint features using the pitch and tone, only the pitch and tone of a certain voiceprint feature of the audio signal are matched with the pitch and tone of the voiceprint feature in the feature model library, so as to determine whether the voiceprint feature is consistent with the voiceprint feature in the feature model library. If so, indicating that the voiceprint feature belongs to the voiceprint feature of the target object, and storing the audio signal corresponding to the voiceprint feature as a recording signal; if not, the voiceprint feature does not belong to the voiceprint feature of the target object, and the audio signal corresponding to the voiceprint feature is discarded.

Specifically, the pitch represents the height of a sound (treble, bass), and is determined by "frequency", and the higher the frequency, the higher the pitch, and the lower the frequency, the lower the pitch. Each user has its own unique tone. The timbre is also called as "sound article", which has different characteristics due to the characteristics of different materials, and the timbre of each person is also different. Since the voiceprint feature of each person has its own feature, the audio signal can be accurately filtered using the tone and the tone, so that the recording quality can be improved.

s320, reading the starting time of the recording signal corresponding to each voiceprint characteristic in the recording signals with the same voiceprint characteristics;

and S330, marking the starting time of the identified sound recording signals with the same voiceprint characteristics.

The identification can comprise a start identification and an end identification, wherein the start identification is used for marking the moment when a certain speaker starts speaking, and the end identification is used for marking the moment when the speaker finishes speaking, so that different speakers can be distinguished more accurately.

s430, storing the audio signal corresponding to the playing source as a recording signal;

s440, discarding the audio signal corresponding to the playing source.
