项目摘要

Physiological studies on the production of the focus were conducted through laryngeal electromyography and x-ray microbeam observation of jaw movements. Perceptual studies were also conducted to examine the effect of the prosodic patterns associated with the focus in the perception of the sentence structure.1. Electromyographic study of focus production.A new method of correlation analysis between cricothyroid muscle activity and the resulting FO contour was applied to speech material varying in accentedness and focal conditions. It was found that the strong suppression of the sternohyoid muscle activity under focus. The suppression was stronger in unaccented phrases than in accented ones. The suppression and its relationship to accent can be interpreted proposed based on the notion of laryngeal state function proposed in Atkinson (1978).2. X-ray microbeam study of jaw movement in the production of focus.It has generally been acknowledged that the fundamental frequency plays a most important role in the production of the focus in Japanese. However, in recent years, it is noted that the focus also affects the segmental features. The present study revealed that the jaw opening in a given accent phrase is larger when the accent phrase is focused. Furthermore, the effect of focus was also seen in a form of the reduction of the jaw opening. Thus, the effect of focus is not a localized phenomenon.Effect of prominence on the perception of the ambiguous sentences.The effects of pitch pattern associated with focus on the syntactic ambiguity resolution of Japanese sentences were studied. The results showed that prosodic cues (pitch pattern) can influence the interpretation of a sentence even when the sentence is strongly semantically biased. The results also showed a limitation to prosodic cues. The prosodic biases alone were not sufficient to fully determine the interpretation of the sentences even when the sentences were neutrally biased semantically.

有关焦点生产的生理研究是通过喉肌电图和X射线微膜观察的颌骨运动进行的。还进行了感知研究，以检查与句子结构感知相关的韵律模式的效果。1。肌电图生产的肌电图研究。甲状腺功能板性肌肉活性与所得的FO轮廓之间的相关性分析的新方法应用于重音和焦点条件的语音材料。发现对聚焦下的胸骨类肌肉活性的强烈抑制。在不重的短语中，这种抑制比重音的短语更强。可以根据Atkinson（1978）中提出的喉状态功能的概念来解释抑制及其与口音的关系。2。 X射线微束研究焦点生产中的颌骨运动。普遍认为，基本频率在日本焦点的生产中起着最重要的作用。但是，近年来，注意到重点也会影响分段特征。本研究表明，当重点重点时，给定的口音短语中的下颌开口更大。此外，还以减少颌骨开口的形式看到了焦点的效果。因此，焦点的效果不是局部现象。突出对歧义句子的感知的影响。研究了与重点对日本句子的句法歧义分辨率相关的音调模式的影响。结果表明，即使句子具有强烈的语义偏见，韵律提示（音高）也会影响句子的解释。结果还显示了韵律线索的局限性。仅韵律偏见也不足以充分确定句子的解释，即使句子在语义上是中性偏见的。
