The Austroasiatic languagesOSS-troh-ay-zee-AT-ik, AWSS- are a large language family spoken throughout mainland Southeast Asia, South Asia and East Asia. These languages are natively spoken by the majority of the population in Vietnam and Cambodia, and by minority populations scattered throughout parts of Thailand, Laos, India, Myanmar, Malaysia, Bangladesh, Nepal, and southern China. Approximately 117 million people speak an Austroasiatic language, of which more than two-thirds are Vietnamese speakers. Of the Austroasiatic languages, only Vietnamese, Khmer, and Mon have lengthy, established presences in the historical record. Only two are presently considered to be the national languages of sovereign states: Vietnamese in Vietnam, and Khmer in Cambodia. The Mon language is a recognized indigenous language in Myanmar and Thailand, while the Wa language is a 'recognized national language' in the de facto autonomous Wa State within Myanmar. Santali is one of the 22 scheduled languages of India. The remainder of the family's languages are spoken by minority groups and have no official status.
