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.
↑ अआइईउThe front vowels ([i], [e], [ɛ], [j]) which are based on the letters e, i, and y.
↑ अआइईThe non-front vowels, which are based on the letters a, o, and u.
↑This is a dipping tone. It looks similar to ã ə̃ ([ ̃ ] (nasalized mark). The dipping tone differs only in being angular in shape, but is not widely supported by IPA fonts.
↑ अआBefore a final /p, t, c, k/, the six tones of Vietnamese are reduced to two.
