Visemes

Visemes are visual representations of speech sounds, specifically the mouth shapes and movements that correspond to spoken words. Think of them as the visual clues your mouth provides when talking, like how lips, teeth, and tongue position change for different sounds. In technology, especially in speech synthesis and lip-syncing for animations or virtual avatars, visemes help create realistic mouth movements that match spoken words, making communication appear more natural and understandable even without sound. They are essential for accurately depicting speech visually, aiding both communication and entertainment applications.
