I assume that you are a college student or a young professional and that you are highly motivated to learn to speak English fluently.
You will do much better if you seek ways in which you can speak English correctly from the very beginning. Strike a careful balance between free speech and forcing yourself to follow a pattern of correct English use. Do everything in your power to use English correctly.
In the early weeks of English study, this may require that you spend more time repeating recorded Spoken English Learned Quickly exercises than in trying to engage in free speech. Later, however, you will need to spend a great deal of time talking with others.
Nonetheless, every time you encounter new syntax in English, use controlled language drills long enough so that your mind becomes thoroughly familiar with correct sentence structure and pronunciation. If you are using the Spoken English Learned Quickly lessons, repeat the exercises until you can say them quickly and accurately with perfect pronunciation.
As you progress in your English study, begin reading English newspaper articles aloud. Look for examples of new vocabulary and sentence format. Mark the sentences, verify the vocabulary, and then read—and repeat from recall memory—the sentences aloud until they become a part of your speech.
