* Non-phonetic: This is the most direct opposite, meaning "not related to sound or pronunciation."
* Semantic: This focuses on the meaning of words, rather than their sound.
* Orthographic: This refers to the spelling of words, which can be different from how they are pronounced.
* Graphetic: This also focuses on written representation, but with a broader view than just spelling.
* Morphological: This refers to the structure of words and their component parts, not their sound.
The best antonym will depend on the specific situation and what aspect of "phonetic" you want to contrast.
