How to improve your spoken English

Improve Your English Speaking and English Pronunciation Skills

The first rule of speaking English is to speak clearly, concisely and use simple vocabulary. KISS - keep it short and simple. Remember you probably won't just speak to native speakers. There are roughly 380 million native speakers, but as many as a billion people speak it as a second language. So it's a good idea to avoid idioms and slang (I always say learn it, but don't use it). It might sound clever to say "You're barking up the wrong tree," but if you misuse it or if the other person doesn't understand you, you'll only look silly when you try to explain what you meant to say, or what it actually means.
