Abstract

The invention provides a reverberation voice processing method and device, electronic equipment and a storage medium, and relates to the technical field of computers, in particular to the technical field of artificial intelligence such as voice technology and deep learning. Comprising the steps of obtaining original voice data; delaying the original voice data to generate first reference voice data; performing sub-band decomposition on the original voice data and the first reference voice data to obtain a first complex signal, a first amplitude spectrum and a first phase spectrum corresponding to the original voice data and a second complex signal corresponding to the first reference voice data; determining a first amplitude mask corresponding to the original voice data according to the first complex signal and the second complex signal; and performing sub-band synthesis on the first amplitude mask, the first amplitude spectrum and the first phase spectrum to obtain reverberation-removed voice data. Therefore, according to the first amplitude mask, the amplitude of the voice in the first amplitude spectrum is enhanced, and the amplitude of the reverberation is weakened, so that the reverberation contained in the voice data is effectively removed, and the voice data is clearer.

Description

technical field [0001] The present disclosure relates to the field of computer technology, in particular to the field of artificial intelligence technology such as speech technology and deep learning, and in particular to a reverberation speech processing method, device, electronic equipment, and storage medium. Background technique [0002] In practical applications, sound sources often radiate sound in all directions. Therefore, when sound waves propagate indoors, they may be reflected by walls, floors, ceilings, etc. A disordered state formed by sound after countless reflections in a space is called reverberation. Too much reverb can result in unclear voice data. Therefore, how to effectively remove the reverberation of speech data has become a key research direction. Contents of the invention [0003] The disclosure provides a reverberation speech processing method, device, electronic equipment and storage medium. [0004] According to a first aspect of the present ...
