Segmental contributions to cochlear implant speech perception

Publication date: Available online 3 December 2018Source: Speech CommunicationAuthor(s): Fei Chen, Yi HuAbstractThe present work assessed segmental contributions to speech perception by listeners who had been bilaterally fitted with cochlear implants (CIs). TIMIT sentences were edited to contain vowels (Vs) (replacing consonants with silence) or consonants (Cs) (replacing vowels with silence) and vowel-consonant (V-C) transitions, then presented to unilaterally or bilaterally fitted CI listeners for recognition. Experimental results showed that segmental interruption had a significant influence on CI speech perception. Vowels contained more perceptual information than consonants, and V-C transitions could significantly improve the intelligibility of V-only or C-only sentences. In addition,...
