Paper Title
Speech Presence Probability based Dual-Microphone System

Abstract
This paper proposes a gain function estimation scheme for dual-microphone system noise reduction. The proposed method based speech presence probability to estimate a necessary parameter a priori SNR for calculating. The performance evaluated in condition of diffuse noise field, and the results ensured speech enhancement algorithm. The proposed method deals with this problem and can be considered as an optimal filter that is appropriate for a wide variety of speech application.
