项目摘要

We investigated the interplay between laryngeal mechanisms, using cross-linguistic acoustic, electroglottographic (EEG), and perceptual data.Our most important achievement is the phonetic description of the voicing contrast of plosives in Tokyo Japanese. We showed that closure voicing is variably produced in word-initial position but maintained in word-medial position. Crucially, fundamental frequency (F0) of the following vowel contributes largely to the distinction between the two plosive series in word-initial position. These results were compared with languages that are undergoing a similar development.We then examined the perception of the voicing contrast in Japanese by native and nonnative listeners. We conducted experiments using synthesized stimuli, with Japanese- and French-speaking listeners. Our results showed that closure voicing is the primary cue for both listener groups, but the sensitivity to F0 is stronger with Japanese than French listeners.Seoul Korean is more advanced in this F0 development, and previous studies also reported a role of voice quality. We recorded EEG data with Korean speakers and found highly variable realization of the voice quality. The only consistency is that vowel is breathier after aspirated and lenis than after fortis plosives.Altogether, we have demonstrated that while some automatic mechanisms explain the interplay between laryngeal behaviors, the production and perception of the laryngeal contrast depend on individual variability as well as language-specific factors, such as phonological structure and prosodic contexts.

本研究利用跨语言声学、电声门图（EEG）和感知数据，研究了喉机制之间的相互作用，最重要的成果是对东京日语中塞音的语音对比进行了语音描述。我们发现，闭合清音是在词首位置产生的，但保持在词中的位置。最重要的是，后面元音的基频（F0）在很大程度上决定了两个爆破音序列在词首位置上的区别。这些结果与正在经历类似发展的语言进行了比较。然后，我们研究了母语和非母语听众对日语语音对比的感知。我们进行了实验，使用合成的刺激，与日语和法语的听众。我们的研究结果表明，关闭发声是两个听众群体的主要线索，但F0的敏感性更强，日本比法国的听众。首尔韩国是更先进的F0的发展，以前的研究也报告了语音质量的作用。我们记录了韩国人的EEG数据，发现语音质量的变化很大。唯一的一致性是，元音是呼吸后送气和lenis比后加强爆破音。总之，我们已经证明，虽然一些自动机制解释了喉行为之间的相互作用，生产和感知的喉对比取决于个人的差异，以及语言特定的因素，如语音结构和韵律上下文。
