Strategic Pauses Relieve Listeners from the Effort of Listening to Fast Speech: Data Limited and Resource Limited Processes in Narrative Recall by Adult Users of Cochlear Implants.

The cochlear implant group had only 15 participants, and one participant stopped after the first block, so accuracy data for that participant were based on three trials in each condition. The study used laboratory narrative passages and a single compression level, 60% of original playing time, so it may not match everyday speech speed, topic changes, noise, or real communication goals. Participants knew the condition before each passage, so expectation could influence performance. The normal-hearing experiment used vocoder simulations, which do not fully capture cochlear implant signals. Cochlear implant users varied widely, with word recognition scores ranging from 20% to 69% correct, making group averages hard to apply to an individual client. The subgroup analysis of who benefited was exploratory and based on small subgroups. Pupil size was used as an effort measure, but it is not a clinical outcome and can reflect arousal or baseline variability.

The authors declared no conflicts of interest. The work was funded by the National Institutes of Health, National Institute on Deafness and Other Communication Disorders.

Do not conclude that adding pauses to everyday speech is a proven clinical treatment for all cochlear implant users. The study tested short narratives in a laboratory, not real-world conversations, and recall did not fully return to normal speech-rate performance for cochlear implant users.
