im going to say it
voice chating with ai bots is good practice

non stressful environment, you can read their responses if you just want to practice speaking and not have to practice listening at the same time, your responses get transcribed so you can see if you made any mistakes, you can have the bot critic you after for mistakes and if there are better phrases you could have used (though taken with a grain of salt)
the one downside is they will start responding as soon as you pause speaking even for a moment which is annoying and not realistic
