利用喉肌电图（EMG）和纤维内窥镜研究了喉调节对日语元音清音和元音间清音的语音变化的作用。结果表明，元音清音伴随着环杓后肌和杓间肌的肌电活动模式不同于全浊元音，导致声门大开。从这一点上可以得出结论，元音清音主要反映了一种比肌电信号更高水平的自由变化。与此相反，发出/h/时声门仍然和发出/h/或/s/时声门一样宽，尽管存在声带振动，但这些肌肉的EMG模式相当。因此，后一种现象可能主要取决于声门水平上的某些其他条件。
The role of laryngeal adjustments for phonetic variations of voicing in Japanese-vowel devoicing and intervocalic/h/voicing–was investigated using laryngeal electromyography (EMG) and fiberoptic endoscopy. The results indicated that the vowel devoicing was accompanied by EMG activity patterns of the posterior cricoarytenoid and interarytenoid different from those for fully voiced vowels, causing the glottis to be wide open. In this respect, it may be concluded that vowel devoicing mainly reflects a kind of free variation at a higher level than the EMG signals. In contrast, the voicing of/h/occurred while the glottis remained as wide as it did for voiceless/h/or/s/with comparable EMG patterns of those muscles, despite the presence of vocal fold vibrations. Therefore, it may be that this latter phenomenon is chiefly dependent on some other condition at the level of the glottis.
