Description

technical field [0001] The invention relates to the field of voice signal processing, in particular to a microphone array voice enhancement communication system and method based on wireless positioning. Background technique [0002] How to effectively improve the communication quality of speech in noisy environment is a difficult problem in speech processing. In a practical application environment, when the microphone picks up voice signals, it will be interfered by signals such as background noise, reverberation, and other speakers' voices. These interferences and noises can significantly reduce the quality and intelligibility of the picked-up speech signal, resulting in degradation of the performance of the speech communication system. Therefore, effective speech enhancement processing is required in many call applications to suppress noise, improve speech quality, and improve speech clarity, intelligibility, and comfort. [0003] At present, speech enhancement methods m...
