This paper deals with the problem of speech enhancement when

only a corrupted speech signal is available for processing. Kalman

filtering is known as an effective speech enhancement technique,

in which speech signal is usually modeled as autoregressive (AR)

model and represented in the state-space domain.-This paper deals with the problem of speech enhancement when only a corrupted speech signa l is available for processing.
