Previous studies of the supralaryngeal correlates of prosodic accentuation in English have shown both an increase in the paradigmatic contrast between phonetic segments and a magnification of the syntagmatic contrast between abutting consonants and vowels in accented words. We analysed tongue and lip movement data from four Australian English talkers in dialogues that elicited accented and deaccented productions of trochaic /bVb/ words. The results showed greater lip aperture magnitudes and peak velocities in the opening and closing gestures of the initial /bV/ syllables and in the opening gestures of the final weak /b«/ syllables. The distance of the rhythmically strong vowels to the centre of the vowel space was generally greater for accented words in both tongue position and formant spaces. The results suggest an enhanced syntagmatic contrast between vowels and consonants in both strong and weak syllables and a marginally greater paradigmatic contrast between the vowel targets in strong syllables.
