Tone height binarity and register in intonation: The case from Kayardild (Australian)

Abstract

Autosegmental-metrical analyses of intonation typically assume a binary opposition between L/H tones, realised as pitch targets within some local pitch range, or register. However, because tone and register can be phonologically independent, a theoretical concern is that an ostensibly three-leveled tone system could be analysed in terms of binary tone plus careful register setting. Plateau contours in Kayardild, based superficially around three tone levels, present a case in point. Arguments are provided that just two phonological tones are involved, plus a form of register control that characterises the entire Kayardild intonational system.
