Brief summary

In this study, the investigators will evaluate whether auditory training with speech-related acoustic features in psychophysical testing will help CI subjects improve speech recognition. The primary endpoint is the speech recognition measures.

Design outcomes

Primary

Measure	Time frame	Description
speech recognition after training	starting 12 months after the award and will take up to 3.5 years to complete	Subjects will be measured for their baseline speech recognition performance (A) and then measured again for speech recognition after receiving auditory training using the psychophysical methods (B). Finally, the subjects will be measured for speech recognition the third time after the training is withdrawn following a ABA longitudinal design.
