I made an application called "Parrot - Pronunciation Practice" for iPhone. It's free. I made it for myself to improve my English pronunciation.

I think it could be helpful for others, so I uploaded it to iPhone App Store (for free). If you're a language learner, check it out. If you know language learners, recommend this app please.
