ab: Summary: This study investigated the temporal coordination of the
    articulators involved in French Cued Speech. Cued Speech is a manual
    complement to lipreading. It uses handshapes and hand placements to
    disambiguate series of CV syllables. Hand movements, lip gestures and
    acoustic data were collected from a speaker certified in manual Cued
    Speech uttering and coding CV sequences. Experiment I studied hand
    placement in relation to lip gestures and the corresponding sound. The
    results show that the hand movement begins up to 239 ms before the
    acoustic onset of the CV syllable. The target position is reached
    during the consonant, well before the vowel lip target. Experiment II
    used a data glove to collect finger gesture. It was designed to
    investigate handshape formation relatively to lip gestures and the
    corresponding acoustic signal. The results show that the handshape
    formation gesture takes a large part of the hand transition. Both
    experiments therefore reveal the anticipatory gesture of the hand
    motion over the lips. The types of control for vocalic and consonantal
    information transmitted by the hand are discussed in reference to
    speech coarticulation. Finally the temporal coordination observed
    between Cued Speech articulators and the corresponding sound was used
    as rules to control an audiovisual system delivering Cued Speech for
    French CV syllables.
