The link between the duration of vowels and their spectral realization has been validated for a long time by Lindblom (1963), i.e. the longer the vowels the more strengthened they are. Similarly, the relation between prosodic constituents of different levels (the prosodic hierarchy) and the duration of phonemes close to their boundaries has been demonstrated (in French, Fougeron 2001; Tabain 2003, 2005). In this study we aim at reproducing these results on non-controlled continuous speech. Procedures that try and detect automatically known prosodic categories are detailed. We show that the higher a vowel is in the prosodic structure of French, the more strengthened it is.
