语音音频和发音运动的年龄和性别匹配的扬声器对已被记录在面对面的互动，同时使用两个电磁发音计（EMA）系统。语言匹配的发言者（AE：AE）与混合语言背景（AE：德国）进行了比较。任务包括同步，模仿和自发的讲话穿插重复的基线话语的相互适应的评价。初始和最终基线任务中元音中点共振峰频率之间的欧几里得距离（ED）显示出与收敛相关的对称减少，对于具有相同语言背景的说话者来说，这种减少更大。为了测试所观察到的减少是否可能是由于疲劳或重复效应，还计算了未参加相同实验的AE扬声器之间的ED。由于这种比较的减少是最小的，因此排除了收敛归因于简单优化的可能性。运动学和动态收敛进行了检查，从基线任务的尾音软腭手势。在峰值速度，传感器路径距离，手势幅度和刚度计算扬声器之间的ED都表现出一致的收敛下降。相关的扬声器内的差异表明，住宿是有效的对称，因为扬声器移向彼此的差异是不是由于实践或疲劳的影响。[Work由NIH支持]
Speech audio and articulatory movements of age- and gender-matched speaker pairs have been recorded in face-to-face interaction using two electromagnetic articulometer (EMA) systems simultaneously. Speakers matched for language (AE:AE) were compared with mixed language backgrounds (AE:German). Tasks included synchronized, imitated and spontaneous speech interspersed with repeated baseline utterances for evaluation of mutual accommodation. Euclidean distances (EDs) between vowel midpoint formant frequencies from the initial and final baseline tasks showed symmetric reductions associated with convergence which were larger for the speakers with the same language background. To test whether the observed reduction might be due to fatigue or repetition effects EDs were also calculated between AE speakers who did not participate in the same experiment. Because reduction was minimal for this comparison the possibility that convergence can be attributed to simple optimization is excluded. Kinematic and dynamic convergence was examined on coda velar gestures from the baseline tasks. EDs in peak velocity, sensor path distance, gesture amplitude and stiffness computed between speakers all showed decreases consistent with convergence. Associated within-speaker differences showed that accommodation was effectively symmetric, and because the speakers moved towards one another the difference was not due to practice or fatigue effects.
