Title
Can You "Read Tongue Movements"?
Abstract
Lip reading relies on visible articulators to ease audiovisual speech understanding. However, lips and face alone provide very incomplete phonetic information: the tongue, that is generally not entirely seen, carries an important part of the articulatory information not accessible through lip reading. The question was thus whether the direct and full vision of the tongue allows tongue reading. We have therefore generated a set of audiovisual VCV stimuli by controlling an audiovisual talking head that can display all speech articulators, including tongue, in an augmented speech mode, from articulators movements tracked on a speaker. These stimuli have been played to subjects in a series of audiovisual perception tests in various presentation conditions (audio signal alone, audiovisual signal with profile cutaway display with or without tongue, complete face), at various Signal-to-Noise Ratios. The results show a given implicit effect of tongue reading learning, a preference for the more ecological rendering of the complete face in comparison with the cutaway presentation, a predominance of lip reading over tongue reading, but the capability of tongue reading to take over when the audio signal is strongly degraded or absent. We conclude that these tongue reading capabilities could be used for applications in the domain of speech therapy for speech retarded children, perception and production rehabilitation of hearing impaired children, and pronunciation training for second language learners.
