Abstract (in Japanese) (See Japanese page) 
(in English) Synthesized speech has undergone significant changes in recent years. However, it has not yet been able to reproduce human-like tones. Therefore, the purpose of this study was to create a talking robot. First, we measured the expiratory flow rate of human speech and analyzed how the reed-type artificial vocal cords behaved depending on the flow rate. As a result, a reed-type artificial vocal fold was obtained that produces sound waves with a fundamental frequency of approximately 140 Hz to 80 Hz. However, the frequency analysis results for the current reed produced a large high-frequency component. Therefore, we will investigate the dimensions and flow rate of the reed-type artificial vocal cords to produce a clean fundamental frequency of 100 Hz.
