To develop fluency in your speech, there is only one way: speak.
To improve you must practise. Practise any way you can. Read aloud, repeat along to podcasts or videos (using the pause button to help you), talk to yourself. Do anything to speak English.
To check you are getting better, record yourself speaking English once a week and listen to the recording. Do you sound better than last week? Do you sound better than last month? Last year?
If you want fluency practice, you can book a lesson with me, face-to-face or on Skype, by sending an email through the contact page.
