The charts below show the way in which the International Phonetic Alphabet (IPA) represents Vietnamese language pronunciations in Wikipedia articles. There are two major standards, one of Hanoi and one of Saigon. Each makes distinctions that the other does not; represented here are the central dialects that make the distinctions of both. Following the examples are common alternate transcriptions of these sounds in the IPA for comparison.

See Vietnamese phonology for a more thorough look at the sounds of Vietnamese.
