Phonetic and Phonological Characteristics of Paralinguistic Information in Spoken Japanese

Kikuo Maekawa

The National Language Research Institute, Japan

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.
