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
