In the typical speech of any language, voicing onset and offset are effortlessly coordinated with articulation as part of the intrinsic coordination of sound production. In this paper, we argue that voicing-articulatory coordination patterns could be shaped by sensory feedback during early speech learning and these patterns persist in mature syllable productions. Our experimental results show that voicing onset is closely associated with the peak velocity and peak amplitude of jaw and upper lip movements for VC syllables in adults. This robust coordination in the onset position may function to increase the salience of VC syllables and provide a phonetically natural explanation for vowels to undergo phonological lengthening and to avoid phonological reduction in word-initial onset position.
在任何语言的典型语音中，发声的起始和结束都能毫不费力地与发音协调配合，这是声音产生内在协调的一部分。在本文中，我们认为发声 - 发音协调模式可能在早期语音学习过程中由感觉反馈塑造而成，并且这些模式在成熟的音节产生中持续存在。我们的实验结果表明，在成年人中，发声起始与VC音节的下颌和上唇运动的峰值速度及峰值幅度密切相关。起始位置的这种稳健协调可能起到增加VC音节显著性的作用，并为元音在词首起始位置进行音系学延长以及避免音系学缩减提供语音学上自然的解释。
