摘要：
In this paper, we research the enhancement of noisy specch signals by use of Kalman Filtering. The corrupted speech signal by adding noises, which have +5 to -5dB low SNR, was used as filter object. The adding noises to be processed are broadband white noise and color noise and without correlation to speech signal. The improvement of SNR about 7 to 10 dB have been achieved.
