Understand that learning a new language takes time and effort. Don't be discouraged by initial difficulties or mistakes. Every mistake is a learning opportunity.
Focus on the basics of English grammar and sentence structure. A good understanding of these fundamentals will make it easier to construct correct sentences and improve your fluency.
The key to improving your English speaking skills is to practice consistently. Set aside time each day to speak English, even if it's just for a few minutes.
Find and watch some English movies and TV programs on the net, listen to English songs, and read English books, articles, and the New York Times.
This may be through a friend or family member willing to speak with you. You could find a language partner or make use of an online tutor.
This is a great way of knowing the areas in which you could improve. You can hear and see the intonation, pronunciation, and grammar.
You know what's important, be patient and persistent, for if you can work regularly then you will indeed speak English fluently.
