Acapella lets me just outright buy a voice and download it for offline use but the voices are somewhat dated now. I don’t mind large on device library and I don’t mind paying once, but I want it to sound good and I want it to work 100% offline (and privately). Also would like a male voice if possible, I know most people seem to prefer female voices I guess, I’ve noticed male ones are harder to find.
Flawless speech(stumbles on numbered bullet points a bit)
Try the southern_English_male_medium for a starter voice(in the Piper models)
After you download a model, turn off Network Permissions for a completely offline TTS.
