Natural Vowel and Consonant Recognition by Laura Cochlear Implantees

To examine perception for different levels of performance, the vowel and consonant confusion data were divided into three groups of subjects: the better, intermediate, and poorer performers. In general, the INDSCAL analyses confirmed the results obtained from the information transmission analyses. However, they also supplemented it with other perceptually relevant cues for cochlear implantees, as well as with the weightings over different perceptual dimensions for different types of performers. These analyses suggest that although all subjects use the same type of information, the better performers are more capable of using these different cues than poor performers.
