| Abstract(in English) | We performed several psychophysical experiments that investigated the effect of frication duration and amplitude rise slope on the distinction by editing waveform of Japanese fricatives /∫i/,/∫u/, and /∫a/. In experiment 1, we found that the percent /∫/ responses increased with frication duration, the rise slope patterns affected the percent /∫/ responses, and the relative importance of the rise slope pattern in percent /∫/ responses depended on frication duration. Tindings in experiment 2 suggested that the rise slope pattern at onset affected the distinction. In experiment 3, the effects of the onset-slope were quantified by using linear rise slopes, and the percent /∫/ responses were drawn in the contour diagram with axes of frication duration and slope steepness. It is concluded that the frication duration and amplitude rise slope at onset are the accoustic cues for discrimination between /∫/ and /t∫/, and the two cues interact each other. |
