How do you speak English without mistakes?

Answer 1

Perfecting your ability in English generally requires at least two things: conscious and self-monitored conversation practice with one or more people who have better English than you do and plenty of reading. The conversation practice helps to improve your usage, grammar, and other aspects that might be an issue (such as pronunciation in some cases), but conversational vocabulary tends to be quite limited. That is why lots of reading is very helpful. Reading also helps to improve usage, etc., but it is mainly useful for expanding your vocabulary. It could also be useful to either write essays, etc., to be checked by someone or have someone check things that you write on a regular basis to help you in your writing ability. Obviously, non-native speakers of English require additional assistance and lots of extra work.

Answer 2

There isn't really a way to speak perfect english. But you can reduce using slang. You can always read books, they are most helpful. Write a diary to keep everyday is useful too. Try and hit the books more often. If possible, speak English most of the time so you can get used to it.
