A virtual person made and driven by AI.
A digital human is like a video-game cashier. It smiles, talks, and never asks for a lunch break.
You meet it in livestream shops. You also see it at help desks and online shows. It saves staff time, but a fake look breaks the spell.
Multimodal AI
A digital human often needs text, voice, and visuals to work as one.
TTS
TTS turns written words into the voice a digital human can speak.
Deepfake
If it looks too real, a digital human can be confused with a deepfake.
