Speaking with ai can be effective or just a waste of time?

Hello guys I hope you’re having a great day!

Genuine question, I really want to benefit from summer vacation by improving my English skills specifically when speaking because i feel like i get stuck most of the time , so lately I’ve been reading books and practice my speaking with ai ( copilot bcs this is the only ai I know that can talks via voicemail) I don’t have anyone from my friends that wants to achieve the same goal so I just deal with ai at the moment and also I’m an introvert person so I get shy if i wanted to upload some apps like hello talk etc . I know this may sound a little bit contradictory but I’m trying my best to change my personality and be a lot bit extrovert . My real question now is speaking with ai is enough and can make me improve Or do I need to interact and talk with a human being ? Please I need your help.🙏🏻
