The Sino-Tibetan languages, in a few sources also known as Trans-Himalayan, are a family of more than 400 languages spoken in East Asia, Southeast Asia and South Asia. The family is second only to Indo-European in terms of the number of native speakers. The Sino-Tibetan languages with the most native speakers are the varieties of Chinese (1.3 billion speakers), Burmese (33 million), and the Tibetic languages (6 million), but many Sino-Tibetan languages are spoken by small communities in remote mountain areas and as such are poorly documented. Unlike Western linguists, Chinese linguists generally include Kra -- Dai and Hmong-Mien languages within Sino-Tibetan.
