| Outline of Final Research Achievements |
We analyzed motor dynamics of articulation and phonation for speech data performed at various different speech rate using electroglottograph, photoglottograph, and high-speed digital imaging. The duration of the glottal opening decreased linearly and almost in equal portion to the duration of each segment regulated by the speech rate. On the other hand, the duration of the glottal closing decreased linearly to the duration of each segment, however, does not decreased less than expected from the decrease of the duration of each segment. This suggested that the motor dynamics of the adduction/abduction motion of the arytenoid cartilages may regulate the range of the duration of the CV segment. This also suggests that dynamics of the adduction/abduction motion of the arytenoids or vocal folds, i.e. phonation strongly affect on the regulation of human speech rate.
