This paper deals with the problem of speech enhancement when a

corrupted speech signal with an additive colored noise is the only

information available for processing. Kalman filtering is known as

an effective speech enhancement technique, in which speech signal

is usually modeled as autoregressive (AR) process and represented

in the state-space domain.-This paper deals with the problem of speech enhancement when a corrupted speech signal wit h an additive colored noise is the only informat ion available for processing.
