Intonation des phrases interrogatives et affirmatives en langue vietnamienne
Minh-Quang VU, Do-Dat TRAN, Eric CASTELLI.
Interrogative and affirmative sentences in Vietnamese language, which have same tones and the same number of syllables, are recorded in order to analyse their intonation shape (F0 evolution) avoiding effect of lexical tones and of co-articulation. Comparisons permit us to characterise differences between question and non-question at sentence prosody level. Then, our work is completed by a perception study; its main goal is to check if sentence nature characteristics are included in the sentence prosody, allowing the auditor to classify questions and non-questions, despite the complex form of this prosody in tonal languages. Results show that information on sentence nature are present at the end of its last demi-syllable and that about 70% of sentences are good classified.
