Abstract (in Japanese) (See Japanese page) 
(in English) "ATR MRI database of Japanese vowel production" was used to evaluate acoustic characteristics of realistic vocal tracts for five Japanese vowels through the measurements of frequency responses from vocal tract solid
models formed by a stereo-lithographic technique. An optimized Aoshima’s time-stretched pulse signal generated from a horn driver unit was introduced into the solid model at the lip end. The response signals of the models were recorded at the model’s glottis. This method permits accurate measurement of acoustic characteristics of the vocal tract including the laryngeal cavity. The results provide a benchmark for testing numerical analysis methods that
have been used to study vocal tract acoustics.
