Abstract

The invention provides a signal processing method and device, a storage medium and an electronic device. The method comprises the steps: obtaining a voice signal received by each microphone in a plurality of microphones, wherein the plurality of microphones form a microphone array; determining a plurality of directions of arrival according to the voice signals received by each pair of microphonesin the plurality of microphones, wherein each pair of microphones corresponds to one direction of arrival; determining a pair of microphones from the plurality of microphones according to the plurality of directions of arrival; and performing signal processing on the voice signals received by the determined pair of microphones to obtain a target voice signal. According to the invention, the problems of high operation and hardware complexity when multiple microphones perform voice signal processing are solved, so that the hardware difficulty and complexity are reduced, the calculation complexity is reduced, and a relatively low calculation time delay effect can be obtained.

Description

technical field [0001] The present invention relates to the field of signal processing, in particular to a signal processing method and device, a storage medium, and an electronic device. Background technique [0002] Speech signal processing is a key technology in the field of human-computer interaction. The microphone array composed of multiple microphones can use spatial domain information to better enhance the speech signal, which plays an extremely important role in the back-end speech recognition. It is the speech signal key technologies for processing. [0003] When performing speech signal processing, complex operations such as matrix operations are performed on the multi-channel input signals received by the microphone array. On the one hand, the complexity of the operation will increase exponentially with the number of microphones, so that the operation time will also increase. On the other hand, to use multiple microphones at the same time, the consistency of the...
