Abstract
The relation between visually perceived palatometric patterns and word recognition was measured using palatometric representations from 16 words shown on a video monitor. Five subjects examined the patterns and identified the words spoken. Words identified at 90% or higher accuracy rate were classified as “recognized.” Virtually immediate recognition of some words and rapid development of recognition for all of the words were found. Few errors were observed in the responses of any subject after the 6th of 10 experimental days. Analysis of the data indicated that word length, consonant manner of articulation, consonant and vowel place of articulation, and movement timing were the visual attributes used to differentiate the palatometric displays. An articulatory feature analysis indicated that the visually perceived attributes of the displays parallel those found in acoustic studies. The findings suggest that phonetic features may not be sensory avenue dependent. The findings will be interpreted with respect to modeling and shaping speech of the deaf.
