Aspects of Visual Speech in Arabic

International audience In this paper, we present a study of visual speech in Arabic. More specifically, we performed a lipreading recognition experiment on Arabic, where a set of consonant-vowel stimuli were presented as visual-only speech and participants were asked to report what they recognized. The overall lipreading scores were consistent with other experiments in other languages. The resulting consonant confusion matrix shows that some of the phonemes were well discriminated, however, for others it depends on the context. Results are discussed based on the category of phonemes and the vowel context.
