Thai Braille (อักษรเบรลล์) and Lao Braille (ອັກສອນເບຣລລ໌) are the braille alphabets of the Thai language and Lao language. Thai Braille was adapted by Genevieve Caulfield, who knew both English and Japanese Braille. Unlike the print Thai alphabet, which is an abugida, Thai and Lao Braille have full letters rather than diacritics for vowels. However, traces of the abugida remain: Only the consonants are based on the international English and French standard, while the vowels are reassigned and the five vowels transcribed a e i o u are taken from Japanese Braille.
