Robinson shows that in the Aita dialect of Rotokas there is a three-way distinction required between voiced, voiceless, and nasal consonants. Hence, this dialect has nine consonant phonemes versus six for Rotokas Proper (though no minimal pairs were found between /g/ and /ŋ/). The voiced and nasal consonants in Aita are collapsed in Central Rotokas, i.e., it is possible to predict the Central Rotokas form from the Aita Rotokas form, but not vice versa. For example, bokia 'day' has /b ~ β/ in both Central and Aita Rotokas, but the second person plural pronoun in Central Rotokas starts with /b ~ β/, /bisi/, but with /m/ in its Aita cognate. Furthermore, Aita was found to have minimal pairs for the voiced labial and alveolar consonants: /buta/ 'time' vs. /muta/ 'taste'. This suggests that the consonant inventory of the ancestor language of Aita and Central Rotokas was more like Aita, and that the small phoneme inventory of Central Rotokas is a more recent innovation.
