Abstract :
We consider an adaptive filtering algorithm for speech parameter estimation and enhancement when the observation noise is colored with no a priori information. The resulting algorithm consists of adaptive filtering procedures that recursively estimate and enhance the parameters of speech plus noise model, and results in /spl sim/3 dB improvement over Gaussian assumption on the excitation source.
