This paper addresses the dual-microphone noise reduction problem in mobile phone application. We propose to use the inter-microphone Posteriori SNR Difference (PSNRD) for Speech Presence Probability (SPP) estimation, which is more robust than the Power Level Difference (PLD) that is often used previously. Additionally, we use the recently reported multichannel minimum variance distortionless response (MVDR) filter for noise reduction. We divide the noises into quasi-stationary and transient… CONTINUE READING
