Sounds of Speech (University of Iowa)
Animated cutaway diagrams showing how your mouth makes each English sound.
What it actually is
For every English consonant and vowel you get an animation of the tongue, lips and vocal folds, a written description of the articulation and video of a speaker producing it — the visual explanation that finally fixes sounds like /θ/, /ɹ/ and the vowel pairs no amount of listening had corrected. Free, from the University of Iowa, no account needed. It is a phonetics reference rather than a practice tool: there is no recording, feedback or drilling, and it covers American English (with separate Spanish and German sections).
