Tactile and Sensory Interactions

Performance on identifying consonant and vowel stimuli through the Tadoma method of speechreading was studied for a deaf-blind, experienced user of Tadoma. For a set of 24 consonants in CV syllables, performance averaged 55%. For a set of 15 vowels and diphthongs in CVC syllables, performance averaged 56%. Confusion matrices derived from the identification tests were analysis for performance on a set of articulatory/phonological features. The results of the feature analysis for consonants indicated that the features voicing, lip rounding, frication, and place were well-perceived; for vowels, the features lip rounding, tenseness, and vertical lip separation were well-perceived.
