| Research Abstract |
We prepared Japanese and English sentences with various intonation patterns as linguistic materials. The sentences were produced by Japanese speakers and American speakers. An Intonation Training Device which uses a personal computer was employed and four sessions were held on different days. Thepurpose of this production experiment was to find out the most effective method for the acquisition of intonation patterns in English and Japanese. We found that the learners made progress to the greatest degree when the intonation curves of sentences by the learners were displayd over those by a native speaker of the language together with their oral production of those sentences. Also, different degrees of difficulty in the acquisition were shown for various types of intonation patterns.
Another production experiment was carried out on the realization of contrastive stress in English and Japanese by the native speakers and the learners of each language. Significant differences were observed in the intonation patterns and the timing control of vowels. Also, the position of the word with contrastive stress in a sentencewas found to have effect on the difficulty of acquisition. Further study examined the naturalness threshold of English stressed vowels for Americans and Japanese learners of English. Conversely, the naturalness threshold of Japanese accented vowels for Japanese speakers was compared to that of Japanese spoken by American learners. We found certain factors, such as phonemic vowel length distinction and a voice-conditioned effect, which exerted an influence on these judgments of naturalness.
