With regard to the English language, the animations are available for the 44 English phonemes (divided into vowels and consonants) and explain with a video and a step-by-step description how to manipulate the different articulators (lips, jaw, tongue, etc) in order to pronounce English sounds.
These animations are really valuable because, apart from the audio video with the explanation about how to articulate the sound, you can also find words in context with the particular sound. Those words will act as extra support so you can consolidate your pronunciation.
In this Web page you will also find an interactive diagram showing the different components of the mouth and throat used to articulate the phonemes:
