Investigating the role of harmonic cancellation in speech-on-speech masking.

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 investigated the role of harmonic cancellation in the intelligibility of speech in "cocktail party" situations. While there is evidence that harmonic cancellation plays a role in the segregation of simple harmonic sounds based on fundamental frequency (F0), its utility for mixtures of speech containing non-stationary F0s and unvoiced segments is unclear. Here we focused on the energetic masking of speech targets caused by competing speech maskers. Speech reception thresholds were measured using seven maskers: speech-shaped noise, monotonized and intonated harmonic complexes, monotonized speech, noise-vocoded speech, reversed speech and natural speech. These maskers enabled an estimate of how the masking potential of speech is influenced by harmonic structure, amplitude modulation and variations in F0 over time. Measured speech reception thresholds were compared to the predictions of two computational models, with and without a harmonic cancellation component. Overall, the results suggest a minor role of harmonic cancellation in reducing energetic masking in speech mixtures.
