A comparison of the listening speed of the Korean TTS for the blind: Based on their screen reader experiences

Abstract

The purpose of this study was to examine the listening speed of the Korean TTS for the blind based on their screen reader experiences. Among ten participants, five people have used a screen reader and the other five had few experiences of using a screen reader. Participants were asked to recall what they heard after they listened to the same sentences for ten repeated sentence sets, and they were asked to recall what they heard after they heard different sentences for the five random sentence sets. For all sentence sets, sentences were provided with fifteen differentiated speeds ranged from 0.8 to 3.6. The results showed that there were positive correlations between participants' screen reader experiences and their listening speed of the Korean TTS, and between the familiarity of sentences and the differences in the listening speed. © 2014 Springer International Publishing.
