AI Article Synopsis
- Cochlear implant (CI) users struggle more than normal-hearing (NH) listeners when it comes to identifying the sex of a speaker and understanding sounds from different directions.
- The study tested how well NH, bilateral CI, and bimodal CI listeners could recognize sentences amid competing sounds that were either placed together or apart, focusing on whether the competing voices were the same or different genders.
- While NH listeners benefited significantly from recognizing the gender and location of the competing voices, CI users only saw some improvement when they could tell the gender of the sound, but not when it came to distinguishing where the sounds were coming from.
Article Abstract
Cochlear implant (CI) users have greater difficulty perceiving talker sex and spatial cues than do normal-hearing (NH) listeners. The present study measured recognition of target sentences in the presence of two co-located or spatially separated speech maskers in NH, bilateral CI, and bimodal CI listeners; masker sex was the same as or different than the target. NH listeners demonstrated a large masking release with masker sex and/or spatial cues. For CI listeners, significant masking release was observed with masker sex cues, but not with spatial cues, at least for the spatially symmetrically placed maskers and listening task used in this study.
