Abstract
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 (MIXMAX) 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.
