Abstract(in English) We have performed studies and evaluation experiments of more acceptable rapid speech,aimed at implementation in applications such as installation in commercial devices designed for visually impaired persons. Although our method's playback time is same as the conventional High-speed playback tecnology,listener might feel playing in slower speeds and listen words clearer. Our proposal technology makes it possible to adaptive speech rate control in utterance positionand pitch/power in the speech information,instead of changing the speed of the utterance uniformly. We performed an experiment with visually impaired persons to compare the conventional high-speed playback technology and that of our adaptive high-speed playback technology in terms of"Listenability". The reaction to our proposal method from subjects with visual impairments has been very positive underscoring its potential as an effective tool for listening to high-speed speech.
