Speech processing to aid the profoundly deaf

Single-chanhel Tactile Aid for the Profoundly Deaf

In this study of lipreading with supplementary tactile input, normally hearing subjects with noise masking were presented with tactile information relating to the voiced/unvoiced contrast. Considerable training was required before subjects were able to make use of this information so as to gain higher scores for lipreading with tactile Supplement than for lipreading alone . These results are in...

Speech-like cerebral activity in profoundly deaf people processing signed languages: implications for the neural basis of human language.

For more than a century we have understood that our brain's left hemisphere is the primary site for processing language, yet why this is so has remained more elusive. Using positron emission tomography, we report cerebral blood flow activity in profoundly deaf signers processing specific aspects of sign language in key brain sites widely assumed to be unimodal speech or sound processing areas: ...

Effects of a Wearable, Tactile Aid on Language Comprehension of Prelingual Profoundly Deaf

Factors influencing the use of nonacoustic aids (such as visual displays and tactile devices) with the hearing impaired are reviewed. The benefits of tactile devices in improving speech reading/lipreading and speech are pointed out. Tactile aids which provide information on rhythm, rate, intensity, and duration of speech increase lipreading and therefore facilitate gains in language comprehensi...

How do Profoundly Deaf Children Learn to Read?

Reading requires two related, but separable, capabilities: (1) familiarity with a language, and (2) understanding the mapping between that language and the printed word (Chamberlain & Mayberry, 2000; Hoover & Gough, 1990). Children who are profoundly deaf are disadvantaged on both counts. Not surprisingly, then, reading is difficult for profoundly deaf children. But some deaf children do manage...
