Speech enhancement method and system, communication device

Abstract

The invention discloses a voice enhancement method, system and communication equipment. Wherein, the method includes: acquiring a voice input signal; performing time-frequency compensation on the voice input signal; calculating a plurality of voice feature information after time-frequency compensation, and classifying the voice input signal to obtain a voice classification result; according to the multiple voice feature information and the speech classification result to determine a speech masking value; based on the speech masking value, determine a speech output signal. The invention solves the technical problem that the voice enhancement method in the related art adopts a fixed mask value, which will leave a lot of noise or damage the voice of the target object, resulting in poor call effect.

Description

technical field

[0001] The present invention relates to the technical field of voice processing, in particular to a voice enhancement method and system, and a communication device. Background technique

[0002] In the related art, when a microphone is used, it is often difficult to hear the voice of the other party due to the noise generated by the surrounding environment or the voice of the surrounding speaker, resulting in a poor call effect. In response to this situation, the dual-microphone sound enhancement method is adopted in the prior art. This dual-microphone sound enhancement method mainly uses various characteristic information (such as dual-channel time difference) to enhance the voice of the other party. Currently, the feature information is being collected. when using figure 1 shown in the microphone topology, figure 1 It is an optional topological structure that uses a microphone to enhance speech in the prior art, figure 1 The head model in represents that...
