ラーオ族
In Laos, the Lao people also refer to the language as "Phasa Lao" (, ), but when necessary to distinguish it from the dialects as spoken in Laos, the terms "Phasa Tai Lao" ( ), 'Lao language of Thailand' (can also mean 'language of the Lao people') as well as "Phasa Lao Isan" (, ), 'Isan Lao language', can also be used. In most other languages of the world, 'Isan' or translations of 'Northeastern Thai language' are used.
