Abstract :
The problem of speaker localization is addressed in this work. We present a novel approach for estimating the time difference of arrival (TDOA) of the speech signal to a microphone array, in a reverberant and noisy environment. By estimating acoustical transfer function (ATF) ratios, the TDOA is extracted from a relatively short impulse response. Our approach shows superior performance, compared with the traditional generalized cross correlation (GCC) method.
