Cochlear Implant Speech and Non-speech Sound Recognition

Stopped early

Conditions studied: Deafness, Sound Perception, Quality of Sound

In brief

The primary purpose of the research is to study how synthesized speech and non-speech percepts (sounds) are recognized in subjects with cochlear implants (CI) who are not getting functional speech recognition using existing speech to CI algorithms. By identifying a partial set of phonemes (units of speech) from this CI feedback, a new language could be developed.
