To be honest i didn't try them. My purpose was just to provide a nice UI/UX to the AI voice model.

You didn't try them!? If you have the ChaptGPT app it's super simple and worth a try. I talk to it in French a lot. It gets tedious though, because after almost every question it tries to end the conversation with "let me know if I can do anything else to help". I really want it to pretend to be curious and continue the conversation. I've thought that this could be fixed with some better prompting, so I'm excited to try out this app.

I haven’t tried this app yet, but my attempts at speaking to ChatGPT in Spanish were pretty dull. Almost every sentence the model replied with “Claro!” and tended to repeat itself often
