该研究检查了使用Wave （NDI, Waterloo， ON, Canada）的点参数化方法定义的语言辅音的位置目标。总体目标是确定哪些辅音相对于其他辅音有独特的舌头位置。19名说话者重复元音-辅音-元音（VCV）音节，包括辅音/t， d, s, z, t, k, g/，在对称的元音上下文中/i， u, a/，嵌入在载体短语中。提取每个辅音的目标区域，以舌高度最大点处的x、y、z舌头位置为特征。计算所有辅音对之间的距离和重叠，并将其与上下文目标的距离和重叠进行比较。同源物和后肺泡同源物被发现共享其目标区域的位置。平均而言，肺泡顿音的靶区与肺泡摩擦音的靶区明显不同，而后者的靶区位置又与后肺泡辅音不同。说话者在目标位置上的差异可以部分解释为习惯语速和硬腭特征的差异。(C) 2012美国声学学会。[http://dx.doi.org/10.1121/1.4733542]
The study examined the positional targets for lingual consonants defined using a point-parameterized approach with Wave (NDI, Waterloo, ON, Canada). The overall goal was to determine which consonants had unique tongue positions with respect to other consonants. Nineteen talkers repeated vowel-consonant-vowel (VCV) syllables that included consonants /t, d, s, z, T, k, g/in symmetrical vowel contexts /i, u, a/, embedded in a carrier phrase. Target regions for each consonant, characterized in terms of x, y, z tongue positions at the point of maximum tongue elevation, were extracted. Distances and overlaps were computed between all consonant pairs and compared to the distances and overlaps of their contextual targets. Cognates and postalveolar homorganics were found to share the location of their target regions. On average, alveolar stops showed distinctively different target regions than alveolar fricatives, which in turn showed different target region locations than the postalveolar consonants. Across talker variability in target locations was partially explained by differences in habitual speaking rate and hard palate characteristics. (C) 2012 Acoustical Society of America.
