The lip-jaw space of a French speaker was studied in various contextual conditions for facial animation purposes within the scope of tcxt-to-visual-spccch synthesis. The corpus included the 14 French vowels and six major consonants (/b/, /v/, /z/, /3/, /I/, /R/) in all possible combinations of preceding and following vocalic contexts with /i/, /a/, and /y/. These sounds were realized within a quotation-like carrier sentence. The speech material was simultaneously recorded on an audio and a video support. Both front and profile views of the speaker's face were archived and each phoneme was labelled on the center of its acoustic realization. Nine repetitions of 86 differing allophones were selected and their corresponding video frames were then automatically analysed so that 14 geometric or anatomic parameters were measured on each frame. The analysis of results here presented led us to a structural description of the French labial space that shows the importance of the context on the visual production of allophones.
