Research Abstract

This research project studied measuring methods for articulatory movement of continuous speech and mechanisms of production of consonants. We developed new methods for measuring articulatory gesture and open/close of the glottis during production of consonants; for example, an ultra-high-speed MRI movie generation method and external lighting and sensing photoelectroglottography. We then analyzed articulatory movement and calculated the vocal-tract acoustic characteristics on the basis of the obtained data.
