Fundamental investigations about differential limen (DL) for word-based speech rate variations in Japanese are described. We carry out auditory tests with stimuli made by equally lengthening or shortening a duration of a word in a sentence. We set up the experiments to diffuse the subjects’ focus of attention. When the focus is diffused, the DL value of acceleration increases in several cases. The obtained DLs are 18.9 msec/mora for acceleration and 26.5 msec/mora for deceleration.
