TL;DR

The study investigates how English speakers weight voicing cues in both production and perception. Participants repeated words with [b] or [p] onsets and labeled synthesized tokens varying in VOT and onset f0, and the researchers used discriminant function analysis and logistic regression to compute each individual's cue weighting. Production data revealed a significant negative correlation between VOT and onset f0, whereas perception data trended toward a positive correlation, and no cross‑domain correlations were found, indicating a complex relationship.

Abstract

This study examines English speakers’ relative weighting of two voicing cues in production and perception. Participants repeated words differing in initial consonant voicing ([b] or [p]) and labeled synthesized tokens ranging between [ba] and [pa] orthogonally according to voice onset time (VOT) and onset f0. Discriminant function analysis and logistic regression were used to calculate individuals’ relative weighting of each cue. Production results showed a significant negative correlation of VOT and onset f0, while perception results showed a trend toward a positive correlation. No significant correlations were found across perception and production, suggesting a complex relationship between the two domains.
