Abstract :
Recently, a relative transfer function (RTF) identification method based on the convolutive transfer function (CTF) approximation was developed. This method is adapted to speech sources in reverberant environments and exploits the non-stationarity and presence probability of the speech signal. In this paper, we present experimental results that demonstrate the advantages and robustness of the proposed method. Specifically, we show the robustness of this method to the environment and to a variety of recorded noise signals.
