Audio-visual consonant recognition with the 3M/House cochlear implant.

Eight experienced 3M/House cochlear implant users' consonant recognition was evaluated with videotaped vowel-consonant vowel lists presented in auditory implant only (A), visual (V), and auditory-visual (AV) conditions. All subjects' scores were better than chance. Results revealed that the AV scores were significantly better than the V scores, which were better than the A scores.

A survey of speech and other auditory perception assessment materials used by cochlear implant centers.

A questionnaire assessing the various auditory perception materials used by cochlear implant centers in evaluating cochlear implant candidates and patients was developed, pilot tested, and mailed in August, 1985, to 135 cochlear implant centers. After a follow-up, there was a 45% return rate. The questionnaire sampled responses pertaining to the respondents' demographics, the types of assessment materials they used, and their opinions about speech and other auditory perception tests for evaluating cochlear implant patients.

Effects of noise on NST and NU 6 stimuli.

This study determined how normal-hearing listeners' performance on a nonsense syllable test (NST) was affected by three noise competitors, and how these responses differed from those on the standard NU 6 meaningful word test. Twenty young adult listeners heard the stimuli via earphones and provided verbal responses to the NST and NU 6 items in competition with: white noise, multitalker noise, and white noise which was amplitude modulated by the multitalker noise, each at a 0 dB signal-to-noise ratio. Responses were scored on a whole-word (all-or-none) basis.
