Research of extracting pathological voice's characteristics based on HHT And recognition
Weiping Hu · Computer Engineering and Applications Journal · 2007
This paper mainly proposes the validity of instantaneous energy’s and instantaneous frequency’s standard deviation parameter used as the pathological voice’s characteristics extracted based on HHT,describs the process of extracting characteristics in detail,and recognizes the new characteristic parameter and the MFCC coefficient uses the DHMM model.The result from recognition shows that,A-f standard deviation parameter which based on HHT is more resultful to use on describing pathological voice,distinguish the pathological voice from normal voice more effectively.
