AI Avatar Generator That Makes a Photo Speak Your Audio

Upload one portrait and one audio file. The audio to video models animate the face so the lips and expressions follow the recording, and the finished talking video is ready to download.

AI Avatar Videos from a Single Portrait

Short expressive clips or ten-minute explainers, both from the same two inputs.

AI Talking Avatar Generator

Upload a front-facing portrait and an MP3 or WAV. Avatar Omni Human 1.5 returns a video of that person speaking or singing the track, with lip-sync, expressions, and gestures generated straight from the audio. Output comes in 720p or 1080p.

Clips run up to 60 seconds, and 15 seconds or less gives the sharpest result. Add an optional prompt to steer the scene, the action, or the expression — it reads Chinese, English, Japanese, Korean, Spanish, and Indonesian.

Lip Sync AI for Long Recordings

When the script is a full lesson rather than a social clip, InfiniteTalk takes the same portrait and up to 10 minutes of audio. Lip-sync stays locked at the phoneme level for the whole recording, and the face, hairstyle, clothing, and background hold steady throughout. Output comes in 480p or 720p.

Generate the narration in the Audio tab and bring the file here, then use a prompt to adjust expression and posture. A course module or a product walkthrough gets made without booking a camera or a presenter.

AI Avatar Models in One Place

Two models built for different lengths. Pick Avatar Omni Human 1.5 for short, expressive clips up to 1080p, and InfiniteTalk when the audio runs long.

How to Make an AI Avatar Video in Three Steps

Upload the Portrait

Use a clear, front-facing photo of one person. A plain background and an unobstructed face give the model the most to work with.

Add the Audio

Attach an MP3 or WAV: a recording, or speech you generated in the Audio tab.

Generate, Then Download

Pick the model and resolution, generate, and download the finished clip.

AI Spokesperson Clips for Every Market

One portrait, many languages. Record or generate the script in each language, run the same face through the model, and the campaign has a consistent presenter everywhere without flying anyone in.

Talking Head Lessons Without the Studio

Turn a ten-minute lecture recording into a video with InfiniteTalk. The instructor appears on screen for the full module, and updating the lesson means swapping the audio, not reshooting.

AI Avatar Product Explainers

Give every product a presenter. Pair the listing script from the Audio tab with a brand persona portrait, and the walkthrough video is ready for the product page or a UGC-style ad.

Onboarding Videos That Update Without a Reshoot

Record the policy walkthrough once as audio and give it a consistent presenter with InfiniteTalk, which holds lip-sync across a long recording. When a procedure changes, swap the audio file and the same face delivers the new version.
