本研究探讨了元音-辅音-元音序列中舌头和嘴唇运动的时间相位，其中辅音是双唇塞音/p，B/和元音/i，a，u/之一;只有不对称的元音上下文被纳入分析。四个人参加了。使用磁力计系统记录发音运动。从第一个元音到第二个元音的舌头运动的开始几乎总是发生在口腔闭合之前。从第一元音到第二元音的舌运动轨迹大部分发生在塞音的闭舌过程中。对于所有受试者，随着舌头运动轨迹的增加，舌头运动的开始相对于嘴唇闭合运动的开始更早地发生。辅音发音和元音语境对发音间的时间和舌头运动运动学的影响在不同的受试者之间存在差异。总的来说，结果是兼容的假设，即有一个时间窗口，在此期间，舌头运动可以开始停止在口腔关闭。舌运动相对于塞音闭合的非常早的开始，以及在闭合之前的广泛运动，最有可能在闭合之前产生额外的元音。
This study examined the temporal phasing of tongue and lip movements in vowel-consonant-vowel sequences where the consonant is a bilabial stop consonant /p, b/ and the vowels one of /i, a, u/; only asymmetrical vowel contexts were included in the analysis. Four subjects participated. Articulatory movements were recorded using a magnetometer system. The onset of the tongue movement from the first to the second vowel almost always occurred before the oral closure. Most of the tongue movement trajectory from the first to the second vowel took place during the oral closure for the stop. For all subjects, the onset of the tongue movement occurred earlier with respect to the onset of the lip closing movement as the tongue movement trajectory increased. The influence of consonant voicing and vowel context on interarticulator timing and tongue movement kinematics varied across subjects. Overall, the results are compatible with the hypothesis that there is a temporal window before the oral closure for the stop during which the tongue movement can start. A very early onset of the tongue movement relative to the stop closure together with an extensive movement before the closure would most likely produce an extra vowel sound before the closure.
