The official language of Laos is Lao as spoken and written in Vientiane 

As an official language, it has successfully become the lingua franca between all Lao and non-Lao ethnic groups in Laos. Of course, native Lao is spoken with differing tonal accents and with slightly differing vocabularies as you move from one part of the country to the next, especially in a north to south direction. But it is the Vientiane dialect that is most widely understood.
