What is WAN 2.2 Speech-to-Video?
WAN 2.2 Speech-to-Video is Alibaba's talking head generation model that creates realistic video from audio input and a reference portrait image. The model synthesizes natural facial expressions, lip movements, head motion, and subtle micro-expressions synchronized to the provided speech audio, producing convincing presenter-style video. The model generates natural-looking talking head content that goes beyond basic lip sync, adding head tilts, eye movements, brow expressions, and other facial dynamics that make the output more lifelike. Audio-to-video synchronization is tight, with lip movements closely tracking the phonemes in the speech input. Compared to basic lip sync models that only animate the mouth area, WAN 2.2 Speech-to-Video generates fuller facial animation for more engaging output. Against text-to-video talking head models, the audio-driven approach preserves the speaker's actual voice and delivery. Best suited for talking head video creation, podcast video generation, and virtual presenter content where realistic facial animation synchronized to speech audio creates convincing presenter videos. Available on FairStack at infrastructure cost plus a 20% platform fee.
