Abstract

The invention discloses a microphone array voice signal processing method and device and equipment and a computer readable storage medium. The method comprises the steps: obtaining N paths of initialvoice signals through a microphone array, where N is a positive integer; correcting the initial delay value of each path of initial voice signal according to a preset rule so as to process the initialvoice signal and obtain N paths of intermediate voice signals; and accumulating the N paths of intermediate voice signals, and processing the accumulated intermediate voice signals by using a sub-band technology to obtain a synthetic speech signal. An original voice signal processing method is changed, and the provided voice signal processing method is simple in calculation involved in the delaycorrection of the initial voice signal and low in calculation amount, the speed in processing the initial voice signal by the audio processor is accelerated, and the sound feedback is effectively inhibited by the sub-band technology.

Description

technical field [0001] The present invention relates to the technical field of signal processing, in particular to a microphone array voice signal processing method, device, equipment and storage medium. Background technique [0002] The microphone array is composed of a certain number of acoustic sensors, which are used to sample and process the sound characteristics of the sound field. At present, the algorithms for processing sound characteristics mainly include AGC (Automatic Gain Control, automatic gain control algorithm), AEC (Automatic Echo Control, automatic echo suppression algorithm), AFC (Automatic Feedback Control, automatic feedback control algorithm), ANS (Automatic Noise Suppression , automatic noise suppression algorithm) and AM (Automatic Mixer, automatic audio mixing processing algorithm), etc., these algorithms are widely used and mature, but due to the large amount of calculation of these algorithms, the calculation is relatively complicated, and the proc...
