Problems solved by technology

[0003] However, when the voice assistant is working, the mobile terminal may be in the audio playback stage, and the playback of these audios will bring obstacles to the voice recognition of the voice assistant
For example, when a mobile phone calls, the mobile phone may play a ringtone, and the type and loudness of the ringtone may be different. When the user uses a voice assistant to control the phone to hang up or connect by inputting voice commands, in many cases, the user's The loudness of the sound may be lower than that of the ringtone, or a voice similar to the user's voice may appear in the ringtone, which will cause the user's voice commands to be overwhelmed or interfered by the ringtone, thereby reducing the recognition rate of the voice assistant and making the phone unable to Correctly execute the user's voice command, seriously affecting the user experience

Abstract

A voice signal processing method, electronic device, and computer-readable storage medium, after the target application program on the electronic device is started, the first audio signal collected by the microphone of the electronic device is obtained, and the playback state of the electronic device meets the preset requirements. When the conditions are set, the second audio signal currently played by the electronic device may be acquired, and the first audio signal may be mixed with the interference caused by the second audio signal, and the first audio signal originates from the voice outside the electronic device. When the recognition of the instruction is interfered, based on the solution of the present application, according to the first audio signal and the second audio signal, the interference originating from the second audio signal in the first audio signal is effectively removed, and the audio signal released from the electronic device is reduced. Interference with externally input voice commands improves the signal-to-noise ratio of the first audio signal, increases the probability of the electronic device correctly recognizing voice commands, and improves user experience.

Description

technical field [0001] The present application relates to the technical field of terminals, and in particular to a voice signal processing method, an electronic device, and a computer-readable storage medium. Background technique [0002] With the popularization of mobile terminals, people use mobile terminals in more and more occasions. In some occasions, the user is unwilling or inconvenient to directly operate the mobile terminal with fingers to input instructions. At this time, the voice assistant can be used to receive the voice instruction from the user, analyze the voice instruction and execute it. [0003] However, when the voice assistant is working, the mobile terminal may be in the audio playback stage, and the playback of these audios will bring obstacles to the voice recognition of the voice assistant. For example, when a mobile phone calls, the mobile phone may play a ringtone, and the type and loudness of the ringtone may be different. When the user uses a vo...
