Method and apparatus for target speech acquisition based on microphone array

摘要

A method and apparatus for obtaining a target voice based on a microphone array, the method comprising: receiving (101) voice signals collected based on a microphone array; Determining (102) a preselected target voice signal and its direction; Performing 103 a strong directional gain and a weak directional gain on a preselected target voice signal to obtain a strong gain signal and a weak gain signal; Performing an endpoint detection based on a strong gain signal to obtain an endpoint detection result (104); And performing the endpoint processing on the weak gain signal according to the endpoint detection result, in order to obtain the final target voice signal. The present invention can obtain an accurate and reliable target speech signal, thereby avoiding the adverse effect of target speech quality on subsequent target speech processing.
