Abstract :

Computer Assisted Pronunciation Teaching (CAPT), as a part of Computer Assisted Language Learning (CALL) systems, is one among systems that use Automatic Speech Recognition (ASR) technology to teach correct pronunciation. We present in this paper our experiments to help Algerian (Arabic) young learner having problems with pronunciation of Arabic language to improve their pronunciation skills. The system is based on mispronunciation detection methods where different scores of pronunciation are calculated to decide how the word was badly pronounced in term of quantitative measure. The results obtained have showed that the GLL (Global average Log Likelihood) score detects mispronunciation with  86,66%.

Keywords :

: CALL; CAPT; ASR; pronunciation scoring, mispronunciation detection.
