I removed the Google Speech engine (robotic voice to give human-like voice to apps) and I looking for a new one in F-droid. I interested in both English and Italian voices.
I also have Vosk Keyboard installed, but I think I installed that manually from a link in FlorisBoard.
Dicio is a voice-driven assistant. I think what you asked for was the second item, VoiceNotify. It's not a screen reader, though, just a notification reader. It works well for that. One (or more) of them depends on RHVoice, which provides the engine.
I don't know if any of them provide Italian; I think RHVoice's developers are Russian, since the main default model is Russian. I'm using the english model and out works fine.
