N2 - Hands-free speech telephony and speech recognition in cars suffer from additive noise and reverberation. We propose an iterative blind room impulse response (RIR) estimation algorithm based on an analysis-by-synthesis loop closed around a multi-path generalized sidelobe canceller (GSC). By combining a post-filter with the proposed scheme, optimal speech enhancement in practical situations can be achieved. The algorithm is tested using simulated data and real speech recordings from the AVICAR database.
