This study presents dental, alveolar, retroflex and palatallateral /l̪l ɭ ʎ/ data from three Central Australian languages: Arrernte, Pitjantjatjara and Warlpiri. We examine spectral tilt and spectral moments. Results suggest that Centre of Gravity and Standard Deviation (1st and 2nd spectral moments) are sufficient to characterize the four places of articulation. The retroflex has a concentration of energy at slightly lower frequencies than the alveolar, while the palatal has a concentration of energy at higher frequencies. The dental is characterized by a more even spread of energy. We discuss the possibility of spectral cues to place of articulation across manners of articulation.
