The rhotic contrasts are prosodically restricted in Arabana. The triple contrast only appears following the tonic vowel, which is the first vowel. In other onset positions /ɻ/ is contrastive, but there is no /r/ vs /ɾ/ contrast. There is no contrast in coda positions. We undertook the first-ever production study of Arabana rhotics. Recorded audio materials were independently coded in PRAAT by two trained transcribers. We found the following allophony: /r/ [r, ɾ, ɹ]; /ɾ/ [ɾ, ɹ], /ɻ/ [ɻ]. The /r/ vs /ɾ/ contrast is thus negatively determined, /r/ permits [r] realizations, but /ɾ/ does not. The commonest realization of both /r/ and /ɾ/ is [ɹ]. The phoneme in neutralized coda position is /r/. The high degree of overlap in realizations between /r/ and /ɾ/ accords with reported perception difficulties.This research was supported by ARC Discovery Projects Reconstructing Australia's linguistic past: Are all Australian languages related to one another?
