Abstract

The present application proposes a recording method, device and system. The recording method includes: acquiring a first voice signal collected by a gun-shaped microphone array and a second voice signal collected by a circular microphone array, wherein the gun-shaped microphone array is end-oriented Pointing to the first party to be recorded, the number of the first party is one person; respectively performing beamforming on the first voice signal and the second voice signal, and determining the speaker of the second party to be recorded according to the beamforming output direction, wherein, the number of the second party is one or more people; perform speaker voice separation according to the speaker direction of the first party and the speaker direction of the second party, and obtain the separated voice of the first party and the second party Record voice signals. The method can improve the recording quality, and at the same time realize the separation of the speaker's voice, so as to facilitate the separation of roles during subsequent recording and transcription, and facilitate listening and reviewing.

Description

technical field [0001] The present application relates to the technical field of speech signal processing, in particular to a recording method, device and system. Background technique [0002] The procuratorial organ needs to record the interrogation situation and the content of the question and answer during the interrogation process, which requires considerable manpower. The development of speech recognition technology provides an effective way to solve this problem. [0003] In related technologies, most of the interrogation recordings use ordinary pickup equipment, which may be one or more. The equipment is generally placed on the wall or on the table of the interrogation room to record the voice of the whole interrogation. [0004] However, the interrogation recording equipment in the related art has the following disadvantages: first, the recording equipment is far away from the speaker, and is easily affected by ambient noise and room reverberation, resulting in low r...
