Abstract

The invention provides a sound recording method, device and system. The sound recording method comprises the steps of acquiring a first voice signal collected by a gun type microphone array and a second voice signal collected by a circular microphone, performing beam forming on the first voice signal and the second voice signal, determining the direction of a second party speaker to be recorded according to beam forming output, performing speaker voice separation according to the directions of a first party speaker and the second party speaker, and obtaining a separated recording voice signal of a first party and a second party, wherein the end of the gun type microphone points to the first party to be recorded; the person number of the first party is one; and the person number of the second party is one or more. The method can improve sound recording quality, and achieves speaker voice separation at the same time, so that role separation during subsequent sound recording and transcription is facilitated, and back listening and looking are facilitated.

Description

Technical field [0001] This application relates to the technical field of speech signal processing, and 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 voice recognition technology provides an effective way to solve this problem. [0003] In related technologies, the interrogation recording mostly uses ordinary pickup equipment, which may be one or more. The equipment is generally placed on the wall or table of the interrogation room to record the voice of the entire interrogation. [0004] However, interrogation recording equipment in related technologies has the following shortcomings: First, the recording equipment is relatively far away from the speaker, and it is easily affected by environmental noise and room reverberation, resulting in poor ...
