Does good perception of vocal characteristics relate to better speech-on-speech intelligibility for cochlear implant users?

Nawal El Boghdady, Etienne Gaudrain, Deniz Başkent
2019 Journal of the Acoustical Society of America  
Differences in voice pitch (F0) and vocal tract length (VTL) improve intelligibility of speech masked by a background talker (speech-on-speech; SoS) for normal-hearing (NH) listeners.  ...  Results showed: (1) CI users did not benefit in SoS perception from increasing ΔF0 and ΔVTL; increasing ΔVTL had a slightly detrimental effect on SoS intelligibility and comprehension.  ...  The column "Bimodal user" indicates whether the participant was a bimodal user, and on which ear the hearing aid was.
