Speaking and vocabulary are related but different. Vocabulary: read and write a lot, and not just in "business." Memorization, via lists or spaced repetition (anki or 3x5 cards) is helpful, but just like programming you need to use your skill to improve your skill. Have a dictionary and blank cards at hand while you read and write. Speaking: speak. :-) Read and speak to a mirror. Get into contexts where you have to listen and speak to people.
