Go To Program 28 Speech Enhancement Using a Multidimensional Mixture-Maximum Model Yochay Yeminy 1 Sharon Gannot 1 Yosi Keller 1 1 School of Engineering, Bar-Ilan University, Ramat-Gan, Israel We present a single-microphone speech enhancement algorithm that models the log-spectrum of the noise-free speech signal by a multidimensional Gaussian mixture. The proposed estimator is based on an earlier study which uses the single-dimensional Mixture-Maximum model for the speech signal. The experimental study shows that there is only a marginal difference between the proposed extension and the original algorithm in terms of both objective and subjective performance measures. View pdf
