Reading articles is a great way to broaden your vocabulary and practise your English, but to improve your natural pronunciation make sure to listen to native level speakers and SPEAK OUT LOUD ^_^
Remember we all slip up at times so don't worry about getting it 100% but a little bit of practice imitating will really help to make your English sound more natural and and easy to understand for native speakers.
Send me a suggestion if you want to hear an article read out loud in my next video.
