基于麦克风阵列的语音增强算法研究

Research on Speech Enhancement Algorithm Based on Microphone Array

语音通信为最普通的一种通信模式,在我们的日常生活中发挥着极为关键的效果。然而,在客观场景内,声音势必会因噪音而产生影响。此类噪声与干扰不但会影响声音的可知性,还使声音处理系统的性能急剧恶化。但是,在现实环境中,声音受到噪音和干扰是不可避免的。这些噪声和干扰不仅影响声音的可知性,还使声音处理系统的性能急剧恶化。麦克风阵列语音增强为语音增强中最普遍的一种模式。文章具体讲解了几类比较普遍的麦克风阵列增强算法以及语音扩展算法的仿真处理结果,语音扩展算法可以从噪音声音中尽可能地提取清晰的声音,从而提高语音质量和主观舒适性。

Voice communication is the most basic way of communication and plays a very important role in People's Daily life.However,in the real world,sound is inevitably affected by noise and interference.These noises and disturbances not only affect the intelligibility of sound,but also make the performance of sound processing system deteriorate rapidly.However,in the real environment,it is inevitable that the sound is subjected to noise and interference.These noises and disturbances not only affect the intelligibility of sound,but also make the performance of sound processing system deteriorate rapidly.Microphone array speech enhancement is one of the most commonly used methods in speech enhancement.This paper introduces several commonly used microphone array speech enhancement algorithms and the simulation results of speech expansion algorithms.The speech expansion algorithm can extract as clear a sound as possible from the noise sound,so as to improve the speech quality and subjective comfort.
