The effect of visual speech information on linguistic release from masking.
Article in The Journal of the Acoustical Society of America, 2023. 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
Listeners often experience challenges understanding a person (target) in the presence of competing talkers (maskers). This difficulty reduces with the availability of visual speech information (VSI; lip movements, degree of mouth opening) and during linguistic release from masking (LRM; masking decreases with dissimilar language maskers). We investigate whether and how LRM occurs with VSI. We presented English targets with either Dutch or English maskers in audio-only and audiovisual conditions to 62 American English participants. The signal-to-noise ratio (SNR) was easy at 0 audio-only and -8 dB audiovisual in Experiment 1 and hard at -8 and -16 dB in Experiment 2 to assess the effects of modality on LRM across the same and different SNRs. We found LRM in the audiovisual condition for all SNRs and in audio-only for -8 dB, demonstrating reliable LRM for audiovisual conditions. Results also revealed that LRM is modulated by modality with larger LRM in audio-only indicating that introducing VSI weakens LRM. Furthermore, participants showed higher performance for Dutch maskers compared to English maskers with and without VSI. This establishes that listeners use both VSI and dissimilar language maskers to overcome masking. Our study shows that LRM persists in the audiovisual modality and its strength depends on the modality.
