 It uses the glottal fricative /[h]/ (/[x]/) before /[i]/ and/or /[a]/, where Maipure would use /[t]/, /[k]/, and /[j]/.Also unlike Maipure, the Avane diphthongs /[ai]/ and /[au]/ do not appear to be contracted in stressed syllables.Ethnographer Gilij described the Avane pronunciation as "rude, guttural" compared to the Maipure's "gentle, beautiful" version.
