Abstract

The embodiment of the invention provides a speech processing method, device and equipment, and is applied to a speech system, the speech system comprises a microphone and a loudspeaker, and the method comprises the steps: obtaining a first speech signal collected by the microphone in a preset time period, wherein the first speech signal comprises a user speech signal and a speech signal played by the loudspeaker in the preset time period; acquiring a second speech signal in the preset time period in a cache; according to the first speech signal and the second speech signal, determining the time delay of playing the speech signals in the cache by the loudspeaker; performing calibration processing on the second speech signal according to the time delay to obtain a third speech signal; and processing the first speech signal according to the third speech signal so as to extract the user speech signal from the first speech signal. And the speech processing accuracy is improved.

Description

technical field [0001] The present application relates to the technical field of audio processing, in particular to a voice processing method, device and equipment. Background technique [0002] The user can control the on-board equipment in the vehicle through voice commands. When the user sends out the voice command, the multimedia device in the vehicle may be playing multimedia voice signals such as music and radio, which makes it impossible to accurately recognize the voice command issued by the user. . [0003] The multimedia device usually stores the multimedia voice signal in the cache first, and then plays the multimedia voice signal in the cache. In the related art, after the microphone in the vehicle acquires the voice signal to be recognized (including voice command and multimedia voice signal), the voice signal to be recognized can be processed through the multimedia signal in the buffer to obtain the voice command issued by the user. However, there is usually ...
