Australian English speakers employ both vowel duration and glottalisation to cue coda voicelessness. However, it is unclear how they use these cues in speech perception. Two groups of Australian English listeners (older/younger, n=77) responded to stimuli in which vowel duration and glottalisation were co- varied. Analysis of listeners’ reaction times to stimuli suggests that glottalisation facilitates faster perception of coda voicing when paired with a congruent cue, but results in slower reaction times when paired with a competing cue. Despite age- based differences in production (older speakers use glottalisation less), in perception older and younger listeners used glottalisation in similar ways.
