Refinement of Enhanced Speech Using Hybrid-Median Filter and Harmonic Regeneration Approach
《Journal of Electronic Science and Technology》2014年第3期293-298,共6页Ching-Ta Lu Jun-Hong Shen Kun-Fu Tseng Chih-Tsung Chen 
supported by the NCS under Grant No.NSC 102-2221-E-468-004
This study proposes a post-processor to improve the harmonic structure of a vowel in an enhanced speech, enabling the speech quality to be improved. Initially, a speech enhancement algorithm is employed to reduce the ...

Enhanced Frequency-Domain Frost Algorithm Using Conjugate Gradient Techniques for Speech Enhancement被引量:1
《Journal of Electronic Science and Technology》2012年第2期158-162,共5页Shengkui Zhao Douglas L. Jones 
supported by the Human Sixth Sense Programme at the Advanced Digital Sciences Center from Singapore’s Agency for Science,Technology and Research
In this paper, the frequency-domain Frost algorithm is enhanced by using conjugate gradient techniques for speech enhancement. Unlike the non-adaptive approach of computing the optimum minimum variance distortionless ...
