面向中国英语学习者的计算机辅助发音系统

ABSTRACT In this paper, we summarize the predicted phonetic confusions from our comparative analysis of Cantonese

and English. Then, we describe the context-sensitive rules used to generate variants in the extended pronunciation

lexicon. Finally we present some experimental results using learner data from our CU-CHLOE corpus to demonstrate

the accuracy of our system.

KEYWORDS computer-aided pronunciation; comparative analysis; context-sensitive rules
