Problems solved by technology

[0003] However, such a voice processing method often loses the dynamics of the voice itself, lacks a sense of cadence and frustration, and aggravates the loss of voice signals, resulting in a decline in voice quality.
At the same time, this voice processing method does not bring any improvement to the echo cancellation algorithm

Abstract

The invention provides a voice signal processing method, a voice signal processing device and related equipment. The voice signal processing method comprises the following steps: acquiring a voice signal; acquiring a voice parameter of the voice signal; executing follow-up gain control on the voice signal, wherein the follow-up gain control comprises the steps of calculating a voice energy interval of the voice signal according to voice parameters of the voice signal; determining a target gain according to the voice energy interval and a predetermined energy range; adjusting the voice signal according to the target gain; and performing automatic gain control on the adjusted voice signal. According to the invention, through the processing of the voice signal, the dynamic state of the voice signal is kept in a reasonable amplitude range, and the echo cancellation processing can be matched to improve the echo cancellation effect, so that the audio experience of the whole system is improved.

Description

technical field [0001] The invention relates to the field of voice processing, in particular to a voice signal processing method, device and related equipment. Background technique [0002] In the video conferencing system, the voice signal amplitude is a very important indicator for judging the voice quality. Too large or too small signal not only affects the user's listening experience, but even too large clipping distortion directly affects the echo cancellation of the conference system. processing, resulting in echo generation. Therefore, at present, automatic gain control is often introduced after echo cancellation and noise reduction processing to adjust the voice signal, or combined with gain and limiting methods to control the voice amplitude within a reasonable range and improve the user's subjective auditory experience. [0003] However, such a voice processing method often loses the dynamics of the voice itself, lacks the sense of cadence and frustration, aggrava...
