SPEECH ENHANCEMENT USING HARMONICS REGENERATION BASED ON MULTIBAND EXCITATION
《Journal of Electronics(China)》2011年第4期565-570,共6页Zhang Yanfang Tang Kun Cui Huijuan 
Supported by the National Natural Science Foundation of China (No. 60572081)
This paper proposes an algorithm that adopts the harmonic regeneration as post-processing to improve the performance of speech enhancement using traditional Short Time Spectral Amplitude(STSA).The proposed algorithm a...

SPEECH ENHANCEMENT USING AN MMSE SHORT TIME DCT COEFFICIENTS ESTIMATOR WITH SUPERGAUSSIAN SPEECH MODELING被引量：4
《Journal of Electronics(China)》2007年第3期332-337,共6页Zou Xia Zhang Xiongwei 
the Natural Science Foundation of Jiangsu Province (No.BK2006001).
In this paper,two speech enhancement systems with supergaussian speech modeling are presented. The clean speech components are estimated by Minimum-Mean-Square-Error (MMSE) es-timator under the assumption that the DCT...

SPEECH ENHANCEMENT USING CONSTRAINED SPECTRAL AMPLITUDE SUBTRACTION BASED ON NONCAUSAL A PRIORI SNR被引量：3
《Journal of Electronics(China)》2006年第6期937-942,共6页Wu Hongwei Wu Zhenyang 
Supported by 973 Project of China (No.2002 CB312102)and the National Natural Science Foundation of China (No.60272044).
Two gain forms of spectral amplitude subtraction are derived theoretically without neglecting the correlation of speech and noise spectrum during the period of a fralne. In the implementation, the constrained gain is ...
