Ngarinjin is spoken in the Northern Kimberley
Ranges of northern Western Australia. Coate and Elkin's
description of sounds is often variable: the palatals are
labeled "palato-dental" (except "alveolar" /j/) on the
consonant chart but just as palatals when listed
individually; /l/ is "alveolar" on the chart but
"alveo-velar" in the list. Symbols for plosives suggest
voiced segments, but they are defined as voiceless. Vowels
apparently may appear long. A high central vowel is added
to the five vowels given by Coates and Elkin on the basis
of a remark that this vowel is heard in some words and is
"differentiated by some linguists in Ngarinjin".
