A heteronym (or heterophone) is a homograph: a word that shares the exact same written spelling as another word, but has a different pronunciation and a different meaning.
Heteronyms are notoriously challenging for non-native English speakers because the written letters provide no phonetic hint about the pronunciation. In many English heteronyms, the pronunciation shift is driven by grammatical class: nouns and adjectives frequently place primary stress on the first syllable (/ˈkɒntɛnt/, /ˈdɛzərt/), while verbs place stress on the second syllable (/kənˈtɛnt/, /dɪˈzɜːrt/).
