Patrons Rythmiques et Genres Littéraires en Synthèse de la Parole

Abstract : In the last twenty years, the quality of synthesized speech has greatly improved with the emergence of new TTS techniques, including corpus-based synthesis systems. Yet the rhythmic patterns obtained do not always sound very natural. In this paper, we compare the rhythmic patterns observed in natural and synthesized speech for three literary forms. The aim of the study is to evaluate how rhythm could be improved in synthesized speech. The comparison of the rhythmic patterns is done by analyzing duration in relation to prosodic structure on a set of texts (six rhymes, four poems and two extracts from fairy tales). This approach allows showing that rhythmic differences between synthesized and natural speech are mostly due to the marking of prosodic structure, especially at the level of the intonational phrase. The lengthening rate for accented syllables located at the end of IPs is much more important in synthesized speech than in natural speech.
