Problems solved by technology

[0005] The embodiment of the present invention provides a voice enhancement method and system, and a communication device, to at least solve the 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 a call Poor technical issues
[0007] In this way, the time-frequency compensation adaptive method can be used to solve the problem of poor call effect due to the difference in the characteristics of the two microphones and the difference in the acoustic structure, resulting in a large amount of noise remaining or damage to the voice of the target object.

Abstract

The invention discloses a voice enhancement method and system and a communication device. The method comprises the following steps: acquiring voice input signals; performing time-frequency compensation on the voice input signals; calculating multiple pieces of voice characteristic information subjected to time-frequency compensation, and classifying the voice input signals to obtain a voice classification result; determining a voice masking value according to the multiple pieces of voice characteristic information and the voice classification result; and determining a voice output signal basedon the voice masking value. The method solves the technical problem of poor communication effect due to the fact that large noise is left or sound of a target object is damaged because a fixed masking value is adopted in a voice enhancement mode in related technologies.

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...
