I agree with Nicci and ausbildung, but I'd like to add thinking in English to the list. I believe thinking in English makes you more used to the language and helps making it more natural to you.

Just speak it. If you never speak, you never know how to speak inflently

Listen to music, maybe audiobooks, watch movies/films - to get a grasp of the pronunciation. And then... try to find a native-speaker (or advanced speaker) and practice. Try to immerse yourself in English - you could start reading the news in English etc pp. Good Luck!

1. To speak better, use the audiobooks by headphone. It is much more effective than speakers. These books are helpful for giving speeches or formal presentations. 2. For informal communication via phone or face to face, English series in the American Channels are very useful. 3. For interview type English, watch BBC, CNN and other news channel talk shows. 4. Try to memorize word list with sentences, it is much more helpful in practical field of communication. 5. If you wish to study in US, EU, Australian programs in English, to meet the standard exams prepare early with Barron's word list-at least one year before the exam start the wordlist.

Record your own voice and listen for pronunciation mistakes. Many people hate to hear the sound of their voice and avoid listening to themselves speak. However, this is a very important exercise because doing it will help you become conscious of the mistakes you are making. * Be patient. You can change the way you speak but it won't happen overnight. People often expect instant results and give up too soon. You can change the way you sound if you are willing to put some effort into it. The following are some book references to help you improve your oral English: - Spoken English by R K Bansal and J B Harrison - Pronounce It Perfectly In English by Jean Yates, Barrons Eductional Series. - English Pronunciation For International Students by Paulett Wainless Dale, Lillian Poms.
