Digital waveguide models are commonly used for simulating vocal-tract acoustics based on physiological data. The data are usually obtained from magnetic resonance imaging. The paper details an approach for extracting the model parameters from vowel sounds. The parameters are used in estimating the formant compared with LPC. The tests are carried on Chinese vowels, and the proposed algorithm is proved...
The objective of this paper is to clarify the role of formant frequency in the perception of pitch in whispered Mandarin. A method of instantaneous frequency estimation is applied to the tracking of whispered speech formant frequencies. The formant frequencies data of whispered Mandarin reveal the relationship between the formant frequencies of whispered Mandarin vowels and gender and tone. Furthermore,...
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...
