Problems solved by technology

[0004] However, after the speech signal is concatenated coded, the damage degree of the speech signal at different frequencies is often inconsistent, and the above scheme uses the same enhancement amplitude, that is, the compensation for speech signals with different damage degrees are consistent, which will make the enhancement effect of the damaged speech signal unstable and unable to effectively improve the speech quality

Abstract

The invention provides a voice signal processing method and device, equipment and a storage medium, and belongs to the technical field of artificial intelligence. For a to-be-processed voice signal, a first power spectrum and phase information of the voice signal at each frequency point in a frequency domain are firstly obtained, then the first power spectrum is enhanced by obtaining a frequency band gain value corresponding to each frequency point, and a second power spectrum of each frequency point is obtained; and a target voice signal meeting a voice playing condition is generated according to the second power spectrum and the phase information of each frequency point. According to the processing mode, the power spectrum of each frequency point is enhanced in a targeted manner, so that the enhancement effect of the voice signal is more stable, the voice quality is effectively improved, and the voice intelligibility is enhanced; moreover, no matter whether the to-be-processed voice signal is subjected to cascade coding processing or not, the processing mode can be adopted to enhance the voice signal, and the application range is wide.

Description

technical field [0001] The present application relates to the technical field of artificial intelligence, and in particular to a voice signal processing method, device, equipment and storage medium. Background technique [0002] With the rapid development of mobile communication technology and Internet technology, various application programs with communication functions emerge as the times require, and users can conduct voice calls through such application programs installed on terminals. In order to enable voice connection between terminals located on different networks, multiple codecs, that is, cascaded codes, will appear in the call link. However, the more times of cascaded coding, the more serious the damage of the speech signal, resulting in the inability of both speech parties to understand the speech content of the other party, that is, the decline in speech intelligibility. [0003] The solution to the above-mentioned problem in the related art is usually: to sear...
