I thought that this resource could be missing; but, much to my surprise it is still working. It belongs to Iowa University and its name is "Phonetics Flash Animation Project". Its porpuse is to show phonetics theory from a different perspective, by using animations in order to ilustrate the way we produce the sounds in a language ( American English, Spanish and German are available), making the experience of learning phonetics less boring and more dynamic and enjoyable.
Phonetics
I must thank to them for providing us such tool, in my personal experience it help me a lot during my Phonetics courses, now I will spread the voice for everyone to use it.
Merry Xmas to all!
