InfiniteTalk is an AI talking video generator for creators who turn photos and videos into realistic talking avatars, digital humans, and talking-head videos.

Talking Photo: upload a portrait, add voice or dialogue, and get a natural talking-head video.

AI Singing Avatar: make any photo sing with accurate mouth sync to your song. Create virtual singers, cover videos, karaoke clips, and emotional music performances for entertainment and music channels. AI Lip Sync: replace dialogue on an existing video while keeping the original motion. Swap voiceovers, narration, dubbing, or punchlines with synced mouths—ideal for video-to-video edits and multilingual dialogue replacement. Made for real workflows: UGC product ads, testimonials, marketing hooks, talking product or mascot ads, reaction videos, brand promos, ecommerce Reels, e-learning intros, and digital human series with one consistent face.
