Sound processing method and device and electronic equipment

Abstract

The invention discloses a sound processing method, a sound processing device, electronic equipment and a computer readable storage medium. The method comprises the following steps: in accordance witha plurality of acoustical signals acquired by a microphone array and an image signal which is acquired by a camera, determining a sound pre-processing direction; selecting a pre-processing filter coefficient based on the sound pre-processing direction; implementing pre-processing filtering on the plurality of acoustical signals with the adoption of the pre-processing filter coefficient, so that aninitial signal source signal and an initial noise source signal are obtained; determining an adaptive filter coefficient; and with the adoption of the adaptive filter coefficient, conducting adaptivefiltering on the initial signal source signal and the initial noise source signal, so that an enhanced signal source signal is obtained. With the application of the sound processing method and the sound processing device, the signal source signal can be enhanced, so that the tone quality of sound is improved.

Description

technical field [0001] The present application relates to the field of sound processing, and more specifically, to a sound processing method, a sound processing device, electronic equipment, and a computer-readable storage medium. Background technique [0002] With the popularization of various electronic devices, in order to improve the convenience of controlling the electronic devices, more and more electronic devices provide a voice control function. For example, an electronic device such as a smart phone or a vehicle-mounted device is provided with a voice control function, and a user can control the electronic device by voice to perform a corresponding function. Therefore, the electronic device needs to recognize the voice of the user, so as to know the real intention of the user, so as to control the corresponding functional units to perform the functions required by the user. However, no matter in the home environment where smart phones are used or in the vehicle env...

AI Technical Summary

Problems solved by technology

However, no matter in the home environment using smart phones or in the vehicle environment using vehicle equipment, speech recognition is relatively susceptible to interference from the external environment, especially external noise has a greater impact on speech recognition

[0003] Therefore, the existing sound processing methods have the problems of poor sound quality and low recognition rate.
