Romanization of Lao
From Wikipedia, the free encyclopedia
There are several different Lao romanization systems, i.e. transcriptions of the Lao alphabet in the Latin alphabet.

[edit] History
One standard system was devised in the first half of the 20th century when Laos was a French protectorate. There are two important factors that govern the way Lao - as opposed to Thai or Isan - was transcribed in that system. The first is that the Lao script does not render characters that are not pronounced. This standard was put into place via a royal edict. The idea was both to make it easier for non-ethnic Laotians to read and write Lao, and to differentiate Lao from Thai, which does render characters that are not pronounced. The second factor is that the French system for transcribing sounds was used, hence "ou," for example, instead of "oo" (or "u") for an oo sound. If not for these two factors, Lao and Thai romanization would appear very similar.
The French transcription system is reflected by the BGN and PCGN standards. (See below.)
