Kalman Filtering for Low Distortion Speech Enhancement in Mobile Communications

• This paper presents a model-based approach for noise suppression of speech contaminated by additive noise. AKalman filter based speech enhancement system is presented and its performance is investigated in detail. It is shown that with a novel speech parameter estimation algorithm, it is possible to achieve 10 dB noise suppression with a high total audible quality.
