An error analysis of the word recognition responses of cochlear implant users and listeners with normal hearing was conducted to determine the types of partial information used by these two populations when they identified spoken words under auditory-alone and audiovisual conditions. The results revealed that the two groups used different types of partial information in identifying spoken words under auditory-alone or audiovisual presentation. Different types of partial information were also used in identifying words with different lexical properties. In our study, however, there were no significant interactions with hearing status, indicating that cochlear implant users and listeners with normal hearing identify spoken words in a similar manner. The information available to users with cochlear implants preserves much of the partial information necessary for accurate spoken word recognition.
