Abstract

The present study investigated a bandwidth extension method to enhance telephonespeech understanding for cochlear implant(CI) users. The acoustic information above telephonespeech transmission range (i.e., ) was estimated based on trained models describing the relation between narrow-band and wide-band speech. The effect of the bandwidth extension method was evaluated with IEEE sentence recognition tests in seven CI users. Results showed a relatively modest but significant improvement in the speech recognition with the proposed method. The effect of bandwidth extension method was also observed to be highly dependent on individual CI users.
