A pronunciation respelling is a regular phonetic respelling of a word that has a standard spelling but whose pronunciation according to that spelling may be ambiguous, which is used to indicate the pronunciation of that word. Pronunciation respellings are sometimes seen in word dictionaries.
The term should not be confused with pronunciation spelling which is an ad hoc spelling of a word that has no standard spelling. Most of these are nonce words though some have achieved a certain amount of standardization, e.g., the informal use of the word gonna to represent an informal pronunciation of going to.
