Abstract

The invention relates to a double-person voice separation method and device, electronic equipment and a storage medium, and the method comprises the steps: obtaining a mixed voice signal received by a microphone array, carrying out the short-time Fourier transform of the mixed voice signal, and obtaining a mixed voice signal in a time-frequency domain form; performing a blind source separation algorithm on the mixed voice signal in the time-frequency domain form to obtain a voice signal of a first channel and a voice signal of a second channel; detecting the state of the voice signal of the first channel and the state of the voice signal of the second channel; determining a first voice signal of the first channel and a first voice signal of the second channel according to the state; determining the orientations of the first channel and the second channel, and determining a second voice signal of the first channel and a second voice signal of the second channel according to the orientations of the first channel and the second channel; and performing short-time inverse Fourier transform on the second voice signal of the first channel and the second voice signal of the second channel to obtain voice time domain signals of the two target sound sources, and accurately separating voices.

Description

technical field [0001] The present application relates to the technical field of speech separation, in particular to a method, device, electronic equipment and storage medium for speech separation of two persons. Background technique [0002] Blind source separation is performed on the speech signal collected by the microphone array after reverberation, and the speech signal of each target is obtained. There are many speech residues after blind source separation, and the separation result is not good when there is speech overlap; there may be separation errors between channels when the application scene is switched. Contents of the invention [0003] Based on the above problems, the present application provides a two-person voice separation method, electronic equipment and storage media. [0004] In the first aspect, the embodiment of the present application provides a two-person speech separation method, including: [0005] Acquiring a mixed voice signal received by the...
