An Examination of Sources of Variability Across the Consonant-Nucleus-Consonant Test in Cochlear Implant Listeners

Spectral modulation detection and vowel and consonant identification in normal hearing and cochlear implant listeners

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. Sequential In...

Consonant recognition loss in hearing impaired listeners.

This paper presents a compact graphical method for comparing the performance of individual hearing impaired (HI) listeners with that of an average normal hearing (NH) listener on a consonant-by-consonant basis. This representation, named the consonant loss profile (CLP), characterizes the effect of a listener's hearing loss on each consonant over a range of performance. The CLP shows that the c...

Exploring the parameter space of Cochlear Implant Processors for consonant and vowel recognition rates using normal hearing listeners

This paper explores two specific parameters in cochlear implant processors in terms of their effect on consonant and vowel recognition rates. The two parameters in our study are the compression factor and the number of electrodes in an M of N SPEAK processor. In particular, the aim is to evaluate the values of these parameters required to match the performance of acoustic re-synthesis models to...

Sources of illusion in consonant cluster perception

Previous studies have shown that listeners have difficulty discriminating between non-native CC sequences and licit alternatives (e.g. Japanese [ebzo]-[ebuzo], English [bnif]-[b=nif]) (Berent et al., 2007; Dupoux et al., 1999). Some have argued that the difficulty in distinguishing these illicit–licit pairs is due to a ‘‘perceptual illusion’’ caused by the phonological system, which prevents li...
