Sixth International Conference on Spoken Language Processing
Effect of speaking rate on phone duration was investigated to improve a Computer-Aided Language Learning (CALL) system that teaches Japanese double-mora phoneme pronunciation . The influence of the speaking rate was formulated as a linear regression line for each phone, based on the analysis results of a male speakerís non-sense word utterances. The formulations were used to develop a method to estimate the speaking rate of the utterance over two hypothesis (presence and absence of double-mora phoneme), and decide which of the hypothesis is the more suitable. Experiments indicated that good identification between singleand double-mora phonemes was possible irrespective of the speaking rate.
