A new Portable Speech Rate Conversion System is developed in order to assist elderly listeners in comprehension of rapid speech by slowing the input speech rate. Compared with the former experimental system [1], this system has the following features;
(1) Holding of all features in the former system which enables a user to convert a speech rate as desired by him/her-self on real time, with invariance in pitch as well as small impairments in quality.
(2) Downsizing.
(3) Introduction of new methods for changing speech rate quickly and for absorbing temporal enlargement of speech.
