At www.MimicMethod.com, you learn which pronunciation mistakes you are making, but you can also give feedback to yourself through a technique called "Flow-verlapping."
It involves using the free application Audacity to record yourself mimicking native speech, then playing back both your recording and the native speakers at the same time.
This makes the acoustic differences between your speech and the native's speakers more obvious.
