This paper investigates the use of voicing information as an
additional cue in contrast enhanced frequency shaping (CEFS)
of speech to improve perception in the hearing impaired. The
presented work builds on an existing system combining multiband
compression with contrast enhanced frequency shaping
(MICEFS) to restore the auditory nerve response of a hearing
impaired listener. CEFS can improve the perception of
voiced segments. Hence voicing cues are used to differentiate
segments for processing. Alternative processing for unvoiced
segments is investigated and shown to improve neural representation
of unvoiced segments compared to using MICEFS
