Rythme et synthèse de la parole
Résumé
In the last twenty years, the quality of synthesized speech has improved greatly with the emergence of corpus-based speech synthesis systems. Yet the rhythmic patterns obtained do not always sound very natural. The aim of the paper is to investigate the reason for the lack of naturalness by comparing the rhythmic patterns observed in natural speech and in synthesized speech for three distinct literary forms (poetry, rhymes and fairy tales). The comparison has been done by automatically computing different rhythmic correlates (%V, !V, !C, VarcoV, VarcoC, rPVI, nPVI and CCI), and by analyzing manually the segmentation in prosodic words and the durational patterns observed at this level of phrasing.
