背景/目标：因为手语的主要发音器官是手，所以手语语音学和手语语音学主要关注手，而把其他发音器官当作被动的目标。然而，有大量的研究在手语语法和韵律的非手动发音的作用。目前的研究探讨如何手和头部/身体的运动协调，以实现语音目标。研究方法：运动学数据收集从5个聋人美国手语（ASL）签名，以允许在签署过程中的手，头和身体的运动进行分析。特别是，我们研究如何在生产过程中的ASL标志在这三个语音位置的下巴，额头和躯干移动。结果如下：我们的研究结果表明，与词汇运动向头部的迹象，前额和下巴移动，以促进收敛与手。相比之下，躯干不移动，以促进收敛与手的迹象位于躯干。结论：这些结果表明，非手动发音服务的语音以及语法或韵律的作用，在手语。未来的符号语音学和音系学模型应该考虑到非手动发音器官在符号实现中的运动。
Background/Aims: Because the primary articulators for sign languages are the hands, sign phonology and phonetics have focused mainly on them and treated other articulators as passive targets. However, there is abundant research on the role of nonmanual articulators in sign language grammar and prosody. The current study examines how hand and head/body movements are coordinated to realize phonetic targets. Methods: Kinematic data were collected from 5 deaf American Sign Language (ASL) signers to allow the analysis of movements of the hands, head and body during signing. In particular, we examine how the chin, forehead and torso move during the production of ASL signs at those three phonological locations. Results: Our findings suggest that for signs with a lexical movement toward the head, the forehead and chin move to facilitate convergence with the hand. By comparison, the torso does not move to facilitate convergence with the hand for signs located at the torso. Conclusion: These results imply that the nonmanual articulators serve a phonetic as well as a grammatical or prosodic role in sign languages. Future models of sign phonetics and phonology should take into consideration the movements of the nonmanual articulators in the realization of signs.
