Hello! In order to speak with confidence, you must be able to understand first. If you can’t understand what a native speaker says, you won’t have many options for how to respond. So don’t rush speaking if you aren’t confident in your comprehension. To gain comprehension skills, listen to and read English every day.
If your comprehension is good, then onto speaking: You must practice this as well. Don’t be afraid to “look stupid” or to be wrong. Act like a child - be curious and willing to fail. We have to get used to the way it feels to speak the language eventually. You can connect with a LingQ tutor to talk once a week which will help with your pronunciation and overall abilities, which should help your confidence. Login - LingQ
Good luck!
