Assessing Perceptual Difficulty Across Speech Sound Categories and Contrasts to Optimize Minimal Pair Training.
Article in Journal of speech, language, and hearing research : JSLHR, 2025. 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
purposeUtilizing psycholinguistic methods, this article aims to ascertain the perceptual difficulty associated with distinguishing between different speech sound categories and individual contrasts within those categories, with the ultimate goal of informing the use of minimal pair contrasts in perceptual training.
designUsing eye-tracking in the Visual World Paradigm, adults with normal hearing (
resultsWe measured fixations to minimal pair competitors over time and found that manner and place competitors exhibited greater competition compared to voicing and nasality competitors. Notably, within manner competitors, substantial differences in discrimination difficulty were observed among individual contrasts.
conclusionsConventional views of speech sound perception have often grouped sounds into broad categories (manner, place, voicing, nasality), potentially overlooking the nuanced differences within these groupings, which significantly affect perception. This work is vital for advancing our understanding of speech perception and its mechanisms. Furthermore, this work will help to refine minimal pair treatment strategies in clinical contexts.
