This paper presents duration and formant data for the central vowels /@/ (schwa) and /a/ in Arrernte, a central Australian language. Results show that /@/ has a shorter duration and higher position in the vowel space in metrically prominent syllables, whereas /a/ has a longer duration and no change in formant structure. By contrast, effects of pitch accent are minimal for both vowels.
