It is typically classified as a Sino-Tibetan language, and has some resemblances to Tani farther to the east.
[3] Koro is spoken by about 1,500 people in the Koro-Aka tribe[1] who are found in East Kameng District, Arunachal Pradesh, northeast India.
[7] Researchers hypothesize Koro may have originated from a group of people enslaved and brought to the area.
It notes that Koro has only 9 percent lexical similarity with Hruso Aka, and that it is "highly dissimilar to neighboring languages".
[9][1] In October 2010, the National Geographic Daily News published an article corroborating the findings of the Ethnologue based on research conducted in 2008 by a linguistic team of David Harrison, Gregory Anderson, and Ganesh Murmu while documenting two Hruso languages (Aka and Miji) as part of National Geographic's "Enduring Voices" project.
Mark Post and Roger Blench (2011)[10] propose that Koro is related to Milang in a branch, or perhaps independent family, they call Siangic.
The information from the chart above was collected from the most recent research done on the consonants of Koro.
In Geissler's work (2013), the articulation of /ʋ/ exists and can sound similar to /v/ or /w/ depending on the speaker.
While a phoneme is the smallest unit of sound that can distinguish one word from another, data suggests that /ʔ/ is instead used for other unidentified roles.
It is possible that Anderson's data may have been influenced by the differences in speech between natives or the Hindi language used by his informants.
