Abstract: In recent years, the problem of improving the quality of noisy signal has always been a dilemma, challenging scientists; especially in diffuse noise conditions. There has been great and growing interest in dual-microphone processing for hands-free speech enhancement. In this paper, the author addresses a improvement of coherence based filter in diffuse noise field. Explicit information about speech presence or absence is necessary in many speech processing applications. The proposal algorithm uses a soft speech presence probability as an optimal parameter to process noisy signal in diffuse noise condition. The evaluation proves that, speech application dual-microphone can be incorporated with this efficiency algorithm for pre-processing.
