Speech enhancement based on soft audible noise masking and noise power estimation ?
We propose a perceptual model based speech enhancement algorithm. The proposed algorithm achieves good trade-off between noise suppression and speech distortion. Musical noise is mitigated by adapting attenuation gains according to short-term noise amplitude. Good performance of the algorithm is confirmed through both objective and subjective tests.
