- W2349607731 abstract "A novel short-time spectrum estimation algorithm of speech enhancement based on distortion control is presented to overcome the speech distortion and low speech intelligibility in conventional method.An objective measurement parameter of speech distortion is introduced in the algorithm and a constraint condition is generated according to the parameter.Then,a modified log spectral amplitude estimation algorithm is proposed based on the speech absence probability and masking properties of the human auditory system.Finally,the enhanced speech is obtained by relating the constraint condition with the estimation algorithm.The new algorithm gets a better performance and the trade-off between noise reduction and speech distortions is achieved.Tests on objective measurements combined with informal subjective listening show that the proposed algorithm has a better performance of speech intelligibility without any perceptional musicality than other spectral subtraction algorithms under the same level of SNR and noise reduction." @default.
