Beyond spectral moments: Validating alternative measures of sibilant fricatives using listener ratings of children's speech.
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
Shadle [(2023). J. Acoust. Soc. Am. 153, 1412-1426] proposed that the spectral peak in mid-frequency (FM) is a superior measure of place of articulation of sibilant fricatives to the most commonly used measure, the first spectral moment (M1). It is examined as to whether FM predicts adult listener's ratings of the place of articulation of 2.5-3.5-year-old children's word-initial /s/ and /ʃ/ when compared to M1. Regression models reveal that FM in 3-9 kHz range best predicts listener's ratings of children's fricatives. These results provide additional validation for FM as a measure of fricatives' place of articulation, including in children's speech.
