This is very important for teachers, when they have to teach english, pronunciation is basic, but if you want to improve your english, this is really neccessary.

There I bring you a slideshow I have done myself. There are several exercises about discriminate which word is pronunced with the right phoneme. When you download it, you'll be able to see how it really works, because you'll be able to listen the phoneme, to see if you have done it right or wrong... well, there it is!!
