Microphone array-based target voice acquisition method and device

Abstract

A microphone array-based target voice acquisition method and device, said method comprising: receiving voice signals acquired on the basis of a microphone array (101); determining a pre-selected target voice signal and a direction thereof (102); performing strong directional gain and weak directional gain on the pre-selected target voice signal, so as to obtain a strong gain signal and a weak gain signal (103); performing an endpoint detection on the basis of the strong gain signal, so as to obtain an endpoint detection result (104); and performing endpoint processing on the weak gain signal according to the endpoint detection result, so as to obtain a final target voice signal (105). The present invention can obtain an accurate and reliable target voice signal, thereby avoiding an adverse effect of the target voice quality on subsequent target voice processing.
