| Research Abstract |
In order for Japanese learners of English to acquire native-like sounding natural speech, we attempted to develop a computer program which recognizes and evaluates the extent to which learners' phonetic realization is either close or distant against the teacher speech. We used a DP matching method to make the evaluation program of coalescent assimilation and linking of English sounds embedded in the sample sentences. As the result of comparing the program's evaluations with the human evaluations, considerably high validity and correlation were found, suggesting our automatic recognition and evaluation system will be of use. We also conducted a research on which feedback modality will best help the learner to realize the important aspects of pronunciation in producing better English rhythm. We tested three different modalities against experimental subjects : visual, auditory, and linguistic. As the result, the auditory feedback tended to be best recognized among the three.
