1. A method of identifying a clean speech signal from a noisy speech signal, the method comprising:

  • receiving an observation vector representing a segment of a noisy speech signal;

    estimating a clean speech value and a noise value based on the observation vector;

    using the clean speech value and the noise value to set a gain for a filter; and

    applying the observation vector to the filter to produce a filtered clean speech vector representing a segment of a clean speech signal.
