Do You Have Any Techniques for Teaching Pronunciation?

There's absolutely a technique. To be able to make a sound, you have to hear a sound. So perception is first, then you need to learn how to pronounce it. And then it's all about repetition, building habits. You build the muscle memory so you don't always have to think about it when you're speaking. Then there is a stage that I believe is also very important which is intentional speaking.
