As there is no fundamental frequency in whisper, abstraction of other acoustic characteristics from whispered Mandarin becomes more prominent in speech analysis and synthesis. In this paper, the differences between whispered and voiced vowels in Chinese are statistically analyzed. At first, the formant of whisper is discussed. Then, Gain in whisper is described. Next, tone recognition for whispered...
This paper concentrates on the abstraction of parameters from vocal tract transfer function of Chinese whispered vowels. As there is no fundamental frequency in whispered speech, these parameters become more prominent in speech analysis and synthesis. It is proved that the proposed algorithm for formant estimation is effectual and the gain of vocal tract transfer function can be utilized for tune...
