What are words called that spelled the same but have different pronunciations?

Words spelled the same but pronounced differently are called homographs.

For example:

* bow (to bend) and bow (a weapon)

* read (present tense) and read (past tense)

* wind (air current) and wind (to turn)

It's important to note that homographs are a subset of homonyms, which are words that have the same spelling and pronunciation but different meanings. Homonyms also include homophones, which are words that sound the same but have different spellings and meanings.
