This paper is a study for an improved dynamic glottal model through high-speed imaging (HSI). As is well known, speech production comprises three parts, namely speech source, speech resonance and lip radiation. Among these three parts, speech source is the most important one because it is the basis of speech. In research on speech production, acoustical models of speech source have been well established. But the physiological speech source, that is to say, the activity of glottis is seldom researched, because the vibration of vocal folds is difficult to observe and sample. A study on glottal model was established many years ago (Kong, 2007), and in that model, the static glottis was modeled by four quarters of ellipses in three modes namely normal mode, leakage mode and open mode. The dynamic glottal control function was modeled by an approximation of multiplication of sine and exponential. The problem of the dynamic glottal model is that the control parameters can’t be well explained, though the glottis can be simulated. In this study, more high-speed images were sampled, the image processing was greatly improved and the dynamic glottal control function was modeled with parameters which were significant to speech perception.

A Categorical Perceptual Study on Mandarin Tones by native Dai language speakers in Dehong Autonomous Prefecture

This paper is intended to investigate how the Dai Dialect speaker in Dehong Autonomous Prefecture perceives Mandarin tones. Therefore identification and discrimination experiments are conducted of the four Mandarin tone continuums with Dai Language speakers. The results suggested that the Dai Language speaker’s perception mode of T1-T2 and T2-T4 continuums are Categorical Perception, but for T1-T3, T2-T3, T3-T4 and T1-T4 continuums are not. These findings indicate that Dai language tone system does have a significant influence on the perception of Mandarin tones.

山东蒙阴方言声调声学研究

本文通过声学实验提取基频参数,研究了蒙阴方言的单字调和双字调声调模式。实验结果表明,蒙阴方言有四个单字调:2个降调、1个声调和1个曲折调,其中阴平、阳平、上声、去声的调值分别为213、54、24、42。双字调共有20种组合模式,连读变调后发生归并后共16种。连读变调在前后字都有发生:阴平大部分情况变为只降不升;阳平作前字时未发生变化,作后字时趋于平调;上声变调情况最为复杂;去声在前后字中都未发生变化;此外,蒙阴方言双字调中单字调后接轻声的连读变调模式很有特点,前接单字调基本都发生了变调,后接的轻声调值也各不相同。
