Abstract : In the context of Silent Speech Communication SSC development after total laryngectomy rehabilitation, tongue and lip movements were recorded with a portable ultrasound transducer and a CCD video camera respectively. A list of 60 French minimal-pairs and a list of 50 most frequent French words were pronounced in vocalized and silent mode by one speaker. Amplitude and timing of the articulatory movements were measured and compared in the two modes. This study showed for silent speech, i a reduced duration of words, ii a general hypoarticulation for lips, but non significant changes for tongue movements depending on the type of vowel and consonant.
