Intelligibility of Intermittently Elimineted Speech Waves and Its Application

Abstract

The intelligibility of intermittently eliminated Japanese speech wave is discussed in this paper. In our experiment, a segment of a Japanese speech wave is intermittently removed by varying the erasing duration and the period. Here, ratio of the erasing duration to period are varied from 10:90 to 90:10 every 10 percent. Listening tests for evaluating intermittently eliminated speech wave have been carried out by about 1000 males aged from 21 to 24 years. Experimental results show that the intelligibility falls from 0.1 ms for 1 ms. The intelligibility increase for the erasing period surpassing 2 to 3 ms.
