Hruso language
Hruso, also known as Aka (Angka), is a language of Arunachal Pradesh India. Long assumed to be a Sino-Tibetan language, it may actually be a language isolate. It is spoken by 3,000 people in 21 villages in Thrizino Circle, West Kameng District. The Hruso people inhabit areas of South East Kameng and are concentrated in the Bichom River Valley, and speak English, Hindi, and Miji in addition to Hruso. Bangru (Ləvai), spoken on the Tibetan border, might be related to Hruso, but it seems more likely that it is a dialect of Miji. Locations

The book Hruso by Robert Shafer, notes the two dialects that Hruso is divided into. The first one is known to be recorded by Campbell and the second dialect is known to be recorded by Anderson, Hesslmeyer, and Payne. Also Dialect A has some differentiation in vocabulary when compared to Dialect B. Dialect A is also known to be briefly recorded and is more archaic than dialect B which has very little recording evidence behind it. Dialects A

But these languages are too poorly recorded to form a basis for a conclusion.
