Résumé
Focusing on articulatory gestures as the minimal units of the time-varying behavior of speech organs, this paper discusses, based on a large corpus, how segmental durations are suggestive of the complexity or magnitude of articulatory gestures and their organization in connected speech. A body of evidences tends to show that segmental duration is not random. For illustration, the MOCHA database (Wrench, 1999) contains 13960 phoneme utterances (durations of vowels and consonants, based on the labeling data provided), which ranges from 20 up to about 350 ms. Interestingly, there exist a significant correlation of segmental duration between two subjects reading the same corpus (r=0.66; p
