·  Zamani B., Rahmani M., Akbari A., “Residual Noise Control for Coherence Based Dual Microphone Speech Enhancement”, International Conference on Computer and Electrical Engineering (ICCEE 2008), Thailand
Among various enhancement methods, dual microphone methods are utilized for their low cost implementation and use of spatial noise reduction. In this paper, we present a double microphone noise reduction method for nearby microphones. Our method is based on a modified coherence based filter which reduces correlated noises using cross spectral subtraction. In our proposed method the amount of noise reduction is controlled in order to achieve an acceptable compromise between residual noise and speech distortion. The performance of the enhancement technique is carried out using PESQ measure. Obtained results confirm the ability of the proposed approach to reduce distortion of signal.
