Tongue reading: comparing the interpretation of visual information from inside the mouth, from electropalatographic and ultrasound displays of speech sounds.

This study aimed to determine whether there is any intuitive ability to interpret the images produced by these systems, and to determine whether one tool is more conducive to this than the other. Twenty adults viewed real-time and slow motion EPG and ultrasound silent movies of 10 different linguo-palatal consonants and 4 vowels. Participants selected which segment they perceived from four forced-choice options. Overall, participants scored above chance in the EPG and ultrasound conditions, suggesting that these images can be interpreted intuitively to some degree. This was the case for consonants in both the conditions and for vowels in the EPG condition. PMID: 23489341 [PubMed - in process]
