本研究的目的是测试一个协议的可行性，用于测量协同发音使用舌表面轮廓数据来自超声成像。超声波和声学数据是从英国南部英语的三个发言者那里收集的，同时他们重复了15次三个句子的列表。辅音/t/ in /t/（在“... Ma tasked...”中）的舌面轮廓与/t/ in /iti/（在“... Leigh teased...”中）的舌面轮廓进行了比较，元音// in /k/（在“... Ma cast...”中）的舌面轮廓与/t/进行了比较。最近邻距离计算用于舌表面轮廓的比较。在两个不同的环境中的相同的音素的令牌之间的平均距离舌面轮廓作为衡量音素的敏感性环境的影响。计算结果表明，舌头轮廓在/t/适应的影响，邻近的元音大约三倍以上的舌头轮廓在/tv/适应的影响，邻近的辅音。本文提出的措施，以未来的语音研究，使用超声波和其他发音技术的适用性进行了讨论。
The purpose of this study was to test the feasibility of a protocol for measuring coarticulation using tongue surface outline data derived from ultrasound imaging. Ultrasound and acoustic data were collected from three speakers of Southern British English while they repeated a list of three sentences 15 times. Tongue surface outlines for the consonant /t/ in /ɑtɑ/ (in “…Ma tasked…”) were compared with those for the /t/ in /iti/ (in “… Leigh teased…”) and tongue surface outlines for the vowel /ɑ/ in /ɑkɑ/ (in “… Ma cast…”) were compared with those in /ɑtɑ/. Nearest neighbour distance calculations were used for the comparison of tongue surface outlines. Mean distance in midsagittal tongue surface outline between tokens of the same phoneme across two different environments was taken as a measure of the phoneme's susceptibility to environmental influence. The calculations show that the tongue contour during /t/ adapts to the influence of the neighbouring vowels approximately three times more than the tongue contour during /ɑ/ adapts to the influence of the neighbouring consonants. The applicability of the measure proposed in this paper to future speech research using ultrasound and other articulatory techniques is discussed.
