5th International Conference on Spoken Language Processing
Three Japanese sentences were uttered repeatedly by three speakers with paralinguistic information indicating A(dmiration), D(issapointment), F(ocus), I(ndifference), S(uspicion), and N(eutral). A perception test using all recorded materials revealed that the average correct perception rate was higher than 80 percent. Acoustic analyses revealed the following phonetic characteristics: - Considerable elongation of utterance duration in types A, D, and S. - The first and last morae were more elastic in duration than the others. - Narrowed pitch range in type D and enlarged pitch range in A, F, and S. - Characteristic low pitch at the beginning of types A, D and S. - Delayed accentual peak location in types A, D, and S. - Systematic distributional difference of sentence-final vowels on the F1-F2 formant plane. - Seeming 'Laryngealization' in the initial low-pitched portion of types S, A, and D.
Sound Example - Typical utterances of sentence 1) uttered with paralinguistic information types A,D,F,I,N, and S, plus an utterance of sentence 3) type N.
