Spectral weights for localization and speech-in-speech recognition with spatial separation of talkers on the horizontal plane.
Article in The Journal of the Acoustical Society of America, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
Some previous research has suggested that sound source localization may not rely on the same cues that support the segregation of speech produced by talkers separated in space. The present experiments evaluated spectral weights for the spatial cues underlying these two tasks by filtering stimuli into 1-octave-wide bands and dispersing them on the horizontal plane. Target stimuli were 100-ms bursts of speech-shaped noise or words produced by 24 male and female talkers, and maskers (when present) were sequences of words. For localization in quiet, weights differed depending on the midpoint and band dispersion range, but they were similar for speech and noise stimuli. For bands dispersed between -15° and +15°, weights peaked at 500 and 1000 Hz. Introducing a speech masker changed the magnitude of weights for localization, but not the relative weight by frequency. For speech-in-speech recognition, sequences of masker words produced predominantly informational masking, such that participants had to rely on spatial cues to segregate the target. As for localization, recognition appeared to rely predominantly on spatial cues in the 500- and 1000-Hz bands. Trial-by-trial data suggest that correct word recognition relied on differences in perceived location of target and masker speech for some but not for all participants.
