Study on Vocal Folds Vibration Characteristics Based on HNR in Transmitted Sound Signals1
,-0001,():
In this article, the estimation of Harmonic to Noise Ratio (HNR) in transmitted sound signals with wavelet transform was proposed. When subjects phonate sustained vowels in breathy, falsetto, leakage and pressed mode in normal loudness, the HNR in human voice and transmitted sound signals was estimated and compared. The results indicated that the NHR in transmitted sound signals could accurately image vocal folds vibration modes and characteristics. It would be one of useful measurements for clinical laryngeal disease diagnosis.
