Formant variability is related to vowel duration across speakers.
Article in JASA express letters, 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
This study examined both the between-subject and within-subject relationships between vowel duration and formant variability during productions of both isolated words and connected speech by analyzing three existing datasets (N = 132). A positive between-subject correlation was observed in isolated words and, marginally, in connected speech. This finding is consistent with the idea that individuals who are more variable rely more on feedback-based control for vowel production, as longer durations allow more time for online corrections. Conversely, no such correlation was found within speakers at the trial level, suggesting that individuals do not modify their vowel duration online for each production.
