Recent work has demonstrated that progressively stronger prosodic boundaries result in increasing amounts of lengthening for consonant gestures, both preceding and following the boundary. The present experiment extends these earlier findings by considering kinematic data collected with a magnetometer to determine (1) if vocalic gestures demonstrate lengthening patterns comparable to those of consonantal gestures due to adjacent prosodic boundaries, and (2) if the relative timing of consonant and vowel gestures is affected by adjacent boundaries. A magnetometer system was used to track articulator movements of 3 speakers producing sentences in which a /... C(1)V(1)(#)C(2)V(2).../ sequence was embedded with varying medial boundaries. All subjects demonstrated lengthening of the vocalic articulation before stronger boundaries. Additionally, effects on the relative timing of words spanning a boundary and the relative timing of segments in boundary-adjacent syllables were observed.
近期的研究表明,逐渐增强的韵律边界会导致辅音手势在边界前后的延长量增加。本实验通过考虑用磁力计收集的运动学数据来扩展这些早期发现,以确定:(1)元音手势是否会由于相邻韵律边界而表现出与辅音手势类似的延长模式;(2)辅音和元音手势的相对时间是否会受到相邻边界的影响。使用磁力计系统跟踪3名说话者说出包含/...C(1)V(1)(#)C(2)V(2).../序列且中间边界不同的句子时的发音器官运动。所有受试者在较强边界之前的元音发音都有延长。此外,还观察到了对跨越边界的单词相对时间以及边界相邻音节中片段相对时间的影响。
