1 · What the graph read from it

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.

2 · The registry

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

Although substantial variability is observed in the articulatory implementation of the constriction gestures involved in /ɹ/ production, studies of articulatory-acoustic relations in /ɹ/ have largely ignored the potential for subtle variation in the implementation of these gestures to affect salient acoustic dimensions. This study examines how variation in the articulation of American English /ɹ/ influences the relative sensitivity of the third formant to variation in palatal, pharyngeal, and labial constriction degree. Simultaneously recorded articulatory and acoustic data from six speakers in the USC-TIMIT corpus was analyzed to determine how variation in the implementation of each constriction across tokens of /ɹ/ relates to variation in third formant values. Results show that third formant values are differentially affected by constriction degree for the different constrictions used to produce /ɹ/. Additionally, interspeaker variation is observed in the relative effect of different constriction gestures on third formant values, most notably in a division between speakers exhibiting relatively equal effects of palatal and pharyngeal constriction degree on F3 and speakers exhibiting a stronger palatal effect. This division among speakers mirrors interspeaker differences in mean constriction length and location, suggesting that individual differences in /ɹ/ production lead to variation in articulatory-acoustic relations.
