| Abstract: |
This paper describes a new speech enhancement approach which employs adaptive beta-order minimum mean square error (MMSE) spectral estimation of short time spectral amplitude (STSA) of a speech signal. In the proposed approach, human perceptual auditory masking effect is incorporated into the speech enhancement algorithm. The relationship between the value of beta and the noise masking threshold is considered. The algorithm is based on a criterion by which the audible noise may be masked rather than being attenuated, and thereby reducing the chance of distortion to speech. Performance assessment is given to show that our proposal can achieve a more significant noise reduction and a better spectral estimation of weak speech spectral components from a noisy signal as compared to many existing speech enhancement algorithms. |
