摘要:

针对远场语音信号易受噪声污染的问题,分析了远场语音信号特点,总结出现有语音信号增强方法,提出一种对谱相减法去噪的改进算法设计。并通过仿真与实验证明,此方法有效抑制了去噪后引入的“音乐噪声”,提高了语音信号可懂度。

关键词: 远场语音;去噪;可懂度

Abstract:

This article analyzes the characteristic of the far field speech signals,summarizes the existing methods to improve speech signals,and presents an improved spectral subtraction algorithm to address the problem that far filed speech signals are liable to be polluted by noise.Simulation and experimental results proves that the proposed algorithm is effective in speech signal denoising,and able to restrain the musical noise and enhance intelligibility.

Key words: farfield speech;denoising;intelligibility
