Working Memory Modulates Auditory Perceptual Sensitivity During Speech Planning.
Article in Journal of speech, language, and hearing research : JSLHR, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeWorking memory plays a critical role in speech production. However, how working memory influences speech systems remains unclear. This study aimed to investigate how maintaining a vowel in working memory alters perceptual sensitivity during speech planning.
methodThirty-two healthy adults participated in two experiments. In Experiment 1 (
resultsIn the speaking condition, participants showed higher perceptual sensitivity in congruent trials compared to incongruent trials, indicating that maintaining a vowel in working memory biased auditory target perception during speech planning. No such effect was observed in the reading condition. Additionally, participants exhibited a trend of reduced speech variability in congruent compared to incongruent trials, suggesting that working memory modulates speech outcome. No significant relationship was found between changes in perceptual sensitivity and speech variability across subjects.
conclusionsThese findings suggest that maintaining a vowel in working memory shapes auditory target representations and modulates speech outcomes. This study provides novel evidence for the influence of working memory on speech systems.
