Spanish phonetics – visualisation
The University of Iowa provides a really excellent online phonetics tool:
http://www.uiowa.edu/~acadtech/phonetics/spanish/frameset.html
All the sounds of the Spanish language are illustrated with animations showing the mechanics of the production of the sound, together with step-by-step descriptions.
There are also video clips of a Spanish speaker saying each sound (in isolation and also in various example words).
