Hello Daisy,
I hope this message finds you well.
Pratice often with a knowledgable English speaker. Watch English tv and mimic what they say, but only documentaries and news stories. Some movies have very rough English.
One of the best way to practice oral English Is Find native English speakers and talk to them, or you can read books, articles or something out loud,or you could also record your voice to practice your pronounciation.
Hi Daisy. A good way to improve English is to listen a lot before you find a English exchange partner. Listening is necessary to understand other people in conversation. If your listening is going up, your speaking will become better potentially.
