Abstract

The invention provides a voice separation method and a voice separation device, wherein the voice separation method comprises the steps: obtaining a target voice, enabling the end time of the target voice to be the current time, and enabling the duration of the target voice to be equal to the preset time; segmenting the target voice into a plurality of target voice segments; inputting the plurality of target voice segments into a voice database; inputting the plurality of target voice segments into a separation model for classification, to obtain a voice segment set of each speaker, wherein the separation model comprises at least one voiceprint feature module, the voiceprint feature modules are in one-to-one correspondence with the speakers, the separation models are re-established at least twice, the separation models are established according to the current voice database every time the separation model is established, and the separation models established at any two times are established according to different voice databases. According to the method, correction is carried out through reconstruction to ensure that the target voice segment in the voice segment set is the voice ofthe same speaker, so that the voice separation accuracy rate is improved.

Description

technical field [0001] The present application relates to the technical field of speech processing, and in particular, to a speech separation method and a speech separation device. Background technique [0002] At present, for the separation of multiple speakers, the common practice in the industry is to use hardware devices (such as microphone arrays, two-way microphones, etc.) Speaker separation. [0003] Speaker separation itself is just the operation of classifying human voice audio according to different speakers. It does not involve the identification of the specific identity of the speaker to whom the voice belongs. The identification of the specific identity of the speaker to which the voice belongs belongs to voiceprint recognition (speaker recognition) technology solved problem. [0004] The speaker separation system that relies on hardware such as microphones is limited by the hardware itself, which makes it less flexible to use, and the applicable scenarios are...
