Studies on Sound, Articulability Heirachy and Optimality Theory

我们继续收集前两年的数据，以验证语音/清晰度等级的存在，并在第三年进行分析，我们调查了日语中各种辅音和元音的速率诱导的重音节化过程。其目的是发现是否有发音相关的响亮。从VC到syllahle的转换点是主要的因变量。当16位演讲者的演讲伴随着节拍器的哔哔声时，他们被录了下来。与本文相关的部分响度级为：（a）清塞音<浊塞音，（B）塞音<擦音，（c）阻塞音<响音。计算并比较每个自然类别的转换点的平均值。结果表明，切换点分析密切复制的响度规模。这表明，越早的切换点，更多的努力是必要的，这是适合韵律和语音组织的动态视图。这项研究也支持了ONSET约束是语法的语音成分的基本组成部分的想法。在这个项目中获得的结果在西班牙的第15届国际语音科学大会上提出。修订后的版本即将在伊利诺伊大学的实验室语音学会议上发表。因此，本项目深化了与所谓的响度等级相关的研究。

We continued to compile the data for the first two years in order to verify the existence of sound/articulability hierarchy and analysed it in the third year.We investigated the rate induced resyllabification process for various consonants arid vowels in Japanese. The purpose is to find whether there are articulatory correlates of sonority. The switching point from a VC to a syllahle was the main dependent variable. Sixteen speakers were recorded when they entrained their speech to metronome beeps. The partial sonority scale relevant to the present article is : (a) Voiceless stop <voiced stop, (b)stop <fricative, and (c) obstruent <sonorant. Mean of the switching point for each natural class was calculated and compared. Results show that the switching point analysis closely replicates the sonority scale. This suggests that the earlier the switching point is, the more effort is necessary, which is suitable for a dynamical view of prosodic and phonetic organization. This study also supports the idea that ONSET constraint is a fundamental building block of the phonological component of the grammer.The results obtained in this project were presented at the 15th International Congress of Phonetic Sciences in Spain. The revised version is to be presented at Laboratory Phonology Meeting at Univ of Illinois soon. Thus this project deepened the studies related with the so-called sonority hierarchies.
