The twenty-seven consonants of the Lao alphabet are divided into three tone classes—high (ສູງ ), middle (ກາງ ), and low (ຕ່ຳ )—which determine the tonal pronunciation of the word in conjunction with the four tone marks and distinctions between short and long vowels. Aside from tone, there are twenty-one distinct consonant sounds that occur in the Lao language.
