Effect of speech recognition test presentation on cochlear implant user performance.
Aline Faria de Sousa, Lucas Bevilacqua Alves da Costa, Rubens Vuono de Brito Neto
PMID 41919898WHAT IT FOUND
Cochlear implant users scored higher on speech tests when the tester spoke the sentences aloud than when they heard a recording: live voice beat recorded by 15.58 points for words and 19.07 for sentences in quiet.
In noise the two came out level.
Key findings
01The group scored higher with live voice than with recorded speech in quiet: 69.2 versus 56.2 on the percentage of words repeated correctly, and 53.5 versus 37.9 on the percentage of whole sentences recognised.
02Most participants individually did better with live voice: in quiet, 43 of the 48 scored higher on words when the tester spoke live, by an average of 15.58 points, and the same pattern held in noise, with an average difference of 16.71 points.
03Sentence scores in noise were almost identical between the two modes, 14.59 with live voice and 14.55 with recorded speech, and live voice in noise was the only condition that did not differ significantly from recorded speech in quiet.

What it does not show
Everyone was tested with their own device and in their own listening setup (both ears, one ear, or implant plus hearing aid), so the group mixes very different listeners and the averages hide that. Participants were recruited by convenience at two centres, with no comparison group and no randomisation; each person was compared against themselves across the four conditions. Live-voice testing cannot be blinded, and one audiologist spoke for every participant, so the live-voice results reflect that person's voice and accent and may not transfer to another tester. Children from age five and adults were tested together, and the results are not broken down by age. Recorded speech in noise produced low scores (a mean of 30.8% for sentences) and live voice in quiet produced high ones (a mean of 69.2% for words), so the top and bottom of the scale may be constrained. The authors themselves caution that similar average scores across conditions may still reflect different listening demands. This was a single assessment, so it says nothing about whether either presentation mode predicts how someone hears in daily life or how much they benefit from their implant over time.
Declared interests
The paper states that there was no financial support ('nothing to declare') and gives no other conflicts of interest. It does not say who designed the study or wrote it up.
The easy way to misread this
Do not read this as a reason to switch to live-voice testing. The higher live-voice scores mean a clinic that tests by voice may overestimate how well a patient hears, and the authors recommend recorded materials precisely because a tester's voice, accent and health change from session to session.
