Abstract

The invention provides a sound acquisition method and device based on a microphone array. The method comprises the following steps of acquiring voices in an environment and sounder information in theenvironment by utilizing the microphone array to obtain multi-channel voices, wherein the sounder information comprises sounding directions of sounders and the number of the sounders; converting the multi-channel voices into single-channel voices; carrying out sentence segmentation on the single-channel voices to obtain voice segment data streams containing a preset type of sound; matching the voice segment data streams with each sounder to obtain a single-separated voice of each sounder; and respectively synthesizing the single-separated voice matched with each sounder into a respective voicesegment. The technical scheme provided by the invention is high in applicability, can be suitable for near-field and far-field voice environments, has the characteristics of high sound detection accuracy, and can separate the voices of a plurality of sounders, so that each sounder corresponds to one voice separated voice segment.

Description

technical field [0001] The invention relates to the field of computer information automatic processing, in particular to a sound collection method and device based on a microphone array. Background technique [0002] Voice is one of the most natural and effective means for people to interact with information. When people obtain speech signals, they are inevitably disturbed by ambient noise, room reverberation and other speakers, which seriously affect the speech quality. Speech enhancement and separation as a preprocessing scheme is an effective way to suppress interference. [0003] Voice separation refers to separating the desired voice data from multiple voices, mainly to study how to effectively select and track certain voices in a complex sound environment. Correctly distinguishing the noise and the target speech of interest, enhancing the target speech, and reducing or eliminating the noise are the research goals of speech separation. This problem has been studied b...
