I hate fucking jewgle cause what do you mean these are the gemini TTS voice options, the names tell me nothing the fuck. Their docs voice descriptions are like "gentle" "firm" and then you play the voice and it's a fucking call center jeet in your ears. No demos of the voices either just a half assed script for you to test the API on your own and manually check every voice model.
They won't even say which voices are feminine and masculine because woke.
Anyway you want to use either Aoede, Autonoe, Vindemiatrix, or my personal favourite Laomedeia.
