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 Ho Chi Minh City. Each makes distinctions that the other does not; neither standard is preferred over the other at Wikipedia. The central dialects, which make the distinctions of both, are generally represented in articles here, except if a local pronunciation is clearly more relevant.
^ abBefore a final /p, t, c, k/, the six tones of Vietnamese are reduced to two.
^In isolation, this can be a dipping tone. The usual IPA diacritic for dipping tone is [a᷉ ə᷉], which differs from the nasalization mark [ ˜ ] only in being angular in shape, and is not widely supported by fonts.
