The Bayan languages are a group of languages spoken primarily in the regions of Siberia and parts of Mongolia. They belong to the larger Turkic language family and are characterized by their unique phonetic and grammatical features. The most notable languages in this group include Bayan-Ulgii and Bayan-Khalkha, which are used by various ethnic communities. These languages are important for cultural identity and heritage among the Bayan people. Efforts are being made to preserve and promote these languages, as they face challenges from dominant languages in the region. Understanding and documenting the Bayan languages contribute to the broader study of linguistics and cultural diversity.
