The Upper Tanana Language originally was spoken in only five villages, each with a different dialect. Those villages were Beaver Creek, Scottie Creek, Northway, Nabesna, and Tetlin. Today, the language is only spoken by about 95 people, above the age of 50, in eastern interior Alaska. Depending on the dialect, the Upper Tanana Language has about six to seven phonemic vowels. the primary difference between the dialects is by the pitch of the tone. Also a major factor in the split of different dialects is that different dialects have different vowel inventories.
