1 Predicting the Intelligibility of Cochlear-implant Vocoded Speech from Objective Quality Measure(12) Department of Electrical Engineering, The University of Texas at Dallas, Richardson, Texas75083, USA Chairman:Hung-Chi Yang Presenter: Yu-Kai Wang Advisor: Dr. Yeou-Jiunn Chen Date: 2012.12.12

2 Material and Methods  Experiments  Experiments 1 and 2 listened to vocoded English stimuli  Total of 30 and 24 test conditions,respectively  Experiment 3 listened to vocoded Mandarin Chinese stimuli  total of 20 test conditions,respectively  Twenty sentences, and none of the sentences were repeated.  The order of the test conditions was randomized.  Subjects were given a 5-minute break every 30 minutes during the testing session..

3 Material and Methods  Used objective speech quality measures for predicting the intelligibility of vocoded speech in noisy conditions.  Vocoded English  Vocoded Mandarin Chinesein  This study investigated the performance.  The linear predictive coding (LPC)  The log-likelihood ratio (LLR)  The Itakura-Saito (IS)  The cepstrum (CEP) distance measures
