It’s all about practicing. If you can read and listen, then practice speaking it as well. To better improve your pronunciation, you can use google translator voice option and practice the words. Build your vocabulary by reading books. Don’t start with heavy long readings though. Start small and build up, read sth that interests you, not just for the sack of learning words. Listen to music and watch movies. Don’t be shy to make mistakes, that’s the only way to learn. Hope this helps.
