Abstract / Description of output
Prosodic prominence modulates vowel production and acoustics. In the present study we test if the same effects play out in perception. We test perception of four American English vowel contrasts, varying formants and duration along a continuum. We test how F0-based prominence modulates vowel categorization, and explore the role of vowel duration as an intrinsic and prominence-lending cue. We find that F0-based prominence modulates vowel perception, dependent on vowel height. High vowels undergo perceptual recalibration in line with hyperarticulation, non-high vowels instead reflect sonority expansion. Lengthening of the vowel is interpreted as an intrinsic vowel quality cue, not as prominence. However, both F0-based prominence and duration interact with formants: more prominent F0 and longer duration enhance categorization along the formant continuum, showing a stronger influence of formant cues under prominence. Results thus show a dual influence for F0 and duration. Both independently impact categorization, and additionally mediate formant cue use.
