5th International Conference on Spoken Language Processing
A new articulatory model GENTIANE, elaborated from an X-ray film built on a corpus of VCV sequences performed by a skilled French speaker, enabled us to analyse coarticulation of main consonant types in vowel contexts from a degrees of freedom approach. The data displayed an overall coarticulatory versatility, except for an absolute invariance in the labio-dental constriction point. For consonant types recruiting the tongue, the variance explained by the degrees of freedom of the model evidenced specific compensation strategies: tongue tip compensation betokened the common coronal status of the dental plosive and the post-alveolar fricative; whereas tongue dorsum compensation signed the dorsal nature of the velar plosive.
