Hearing-impaired young adults were tested with a newly developed instrument that requires a discrimination response to assess viseme perception as a component of lipreading performance, indicating that the test data conformed to the expectations of the Rasch model for person measurement.Abstract:
Forty-six hearing-impaired young adults were tested with a newly developed instrument that requires a discrimination response to assess viseme perception as a component of lipreading performance. Stimuli were videotaped sentences that differed on half of the trials from a captioned target sentence by one viseme embedded in the middle of the sentence. Discrimination within six visual categories was tested: gross syllable pattern, consonant articulation--lips, consonant articulation--tongue, vowel articulation--extreme lip shapes, vowel articulation--graded lip shapes, and vowel articulation--jaw movement. Test data were analyzed using an item response theory model. The results indicated that the test data conformed to the expectations of the Rasch model for person measurement. Relationships among subjects' test scores and communication characteristics also were examined. The data provide evidence that the test protocol, at this early stage of development, is useful for assessing at least one perceptual component of lipreading performance.read more

On the context-dependent nature of the contribution of the ventral premotor cortex to speech perception.
Pascale Tremblay,Steven L. Small +1 more
TL;DR: Using fMRI, it is investigated whether there are brain regions that are conjointly active for both speech perception and production, and whether these regions are sensitive to articulatory complexity during both processes, which is predicted by a covert simulation account.

TL;DR: This study aimed to compare hearing instrument output values of instruments fitted to pre-school children in South Africa to the targets prescribed by the DSLm [i/o] (version 5.0) across the frequency range and found that most of the hearing instrument fittings did not match the prescribed targets.
