Use case

AI Talking Avatar Video Generator

One photo plus audio becomes a talking avatar

Photo + audio = a talking avatar
Lip-sync auto-aligned to audio
Persona never drifts across episodes
One-click 9:16 vertical export

What is it

An AI talking avatar turns one portrait photo plus an audio clip into a talking video: lip-sync matches the audio, expressions look natural, and the result can serve as a fixed virtual host. Save the avatar to the Character Library and every downstream video reuses the same face, keeping the persona consistent across episodes. The whole process needs no live filming and no editing experience.

How it works

Done in 4 steps

1
Prepare a portrait photo
Upload a clear front-facing portrait, or generate a virtual persona with AI Image first as a fixed character.
2
Upload voiceover audio
Prepare a voiceover clip (text-to-speech works) as the content the avatar will speak.
3
Generate the talking video
Use AI Avatar to combine the photo and audio; the system aligns lip-sync and expressions automatically.
4
Save the persona and publish
Save the avatar to the Character Library for reuse, then export the vertical cut for TikTok and Reels.

Frequently asked questions

Do I need to be on camera?

No. With just one portrait photo and an audio clip, AI generates a talking avatar — no live filming or shooting required.

How do I keep the same person across episodes?

Save the avatar to the Character Library (reference image + style description); every generation node then reuses that character to keep looks consistent.

Can I publish the video directly to short-video platforms?

Yes. It exports 9:16 vertical by default, sized for TikTok and Instagram Reels — download and upload directly.
