Since the speech enhancement algorithm based on a Kalman/Wiener filter requires a priori knowledge of the noise statistics and is focused on the minimization of the variance of the estimation error of the speech signal, a small estimation error on the noise may lead to a large estimation error. However, an H/sub /spl infin// filter does not require any assumptions and a priori knowledge on the noise statistics and it searches the best estimated signal that has the minimum error from all the… CONTINUE READING
