Soyot
The Soyot people live mainly in the Oka region in the Okinsky District in the Republic of Buryatia, Russia. According to the 2010 census, there were 3,608 Soyots in Russia. Their extinct language was of a Turkic type and basically similar to the Tuvans. Their language has been reconstructed and a textbook has been published. The language is currently taught in some schools in Oka. The Oka River, the largest river flowing down from the Western Sayans into the Angara is called the Ok-hem meaning "an arrow-river" by the Soyots of the Oka River basin.
They live dispersed among the Buryats and now speak the Buryat language.
