Normal-hearing listeners show masking release; or better speech understanding in a fluctuating-amplitude masker than in a steady-amplitude masker; but most cochlear implant (CI) users consistently show little or no masking release even in artificial conditions where masking release is highly anticipated. The current study examined the hypothesis that the reduced or absent masking release in CI users is due to disruption of linguistic segmentation cues. Eleven CI subjects completed a sentence keyword identification task in a steady masker and a fluctuating masker with dips timed to increase speech availability. Lexical boundary errors in their responses were categorized as consistent or inconsistent with the use of the metrical segmentation strategy (MSS). Subjects who demonstrated masking release showed greater adherence to the MSS in the fluctuating masker compared to subjects who showed little or no masking release; while both groups used metrical segmentation cues similarly in the steady masker. Based on the characteristics of the segmentation cues; the results are interpreted as evidence that CI listeners showing little or no masking release are not reliably segregating speech from competing sounds; further suggesting that one challenge faced by CI users listening in noisy environments is a reduction of reliable segmentation cues. © 2015 Acoustical Society of America;
