众所周知，与美式英语 /r/ 的声学感知相关的降低的 F3 可以通过生产中不同的舌头形状来实现。一般来说，这些形状可以分为“束状”和“卷舌”两种。在这项工作中，研究了体感扰动对 /r/ 产生的影响。受试者安装了定制的腭假体，该假体沿牙槽嵴有 0.5 厘米的突出部分，并使用 EMA 在四种条件下观察在发声环境中发出 /r/ 时舌头的位置：假体放置之前；放置后立即佩戴假肢；经过未记录的 20 分钟适应期后仍佩戴假肢；以及假体移除后立即进行。扰动的声学影响很小，特别是在适应之后；生产效应在低元音背景下最为明显。一名受试者表现出对卷舌配置的平静偏好，但增加了...
It is well established that the lowered F3 associated with the acoustic percept of American English /r/ can be achieved with different tongue shapes in production. Broadly speaking these shapes may be grouped into ‘‘bunched’’ and ‘‘retroflex’’ varieties. In this work the effects of somatosensory perturbation on /r/ production are examined. Subjects were fitted with a custom palatal prosthesis incorporating a 0.5 cm protrusion along the alveolar ridge, and tongue position during production of /r/ in vocalic contexts was observed using EMA under four conditions: before prosthesis placement; while wearing the prosthesis immediately following placement; still wearing the prosthesis following an unrecorded 20 min adaptation period; and immediately after prosthesis removal. Acoustic effects of the perturbation were minimal, especially after adaptation; production effects were most pronounced in the low vowel context. One subject showed an unperturbed preference for a retroflex configuration, but increased the d...
