PersonaTalk: Bring Attention to Your Persona in Visual Dubbing
What is PersonaTalk: Bring Attention to Your Persona in Dubbing
PersonaTalk is a research project that makes lip-sync dubbing look and feel like the real speaker. It keeps the person’s speaking style and face details while matching lips to new audio. It was shown at SIGGRAPH Asia 2024 (Conference Track).
PersonaTalk does this with a clear two-step method. First, it builds clean mouth and face motion. Then, it paints the final face with strong detail, so the person still looks like themselves.

How PersonaTalk Works (Simple Walkthrough)
Step 1 — Build the motion: The system takes your audio and mixes in the speaker’s style using a “style-aware audio” step. This drives a template of the face to create lip-synced motion.
Step 2 — Render the face: A “dual-attention” renderer then paints the face. One attention focuses on lips, and the other focuses on the rest of the face, so both look clear and true to the person.
Step 3 — Produce the final video: The system blends the motion and textures to make a clean dubbed clip that keeps identity and keeps mouth timing tight.

The Technology Behind It (Plain English)
- Style-aware audio: The audio is not just “sound.” The model adds the speaker’s style to the audio features, so timing and mouth shapes match, but the feel of speech also matches the person.
- Geometry first: The system builds the face and mouth motion from these styled audio features. Think of this as a clean “motion plan” for the lips and face.
- Dual attention for textures: Two attention steps drive the final look. Lip-Attention locks in crisp, correct mouth details. Face-Attention pulls rich textures for skin, eyes, and hair from strong reference frames.
This two-step flow helps keep both timing and identity strong.

Performance & Showcases
Showcase 1 — Conference highlight with a focus on style and detail PersonaTalk creates lip-sync dubbing while preserving indis' talking style and facial details. It shows strong mouth timing and keeps the person’s look steady across frames. Watch how style carries over while the lips match the words.
Showcase 2 — Another conference clip showing the same strengths PersonaTalk creates lip-sync dubbing while preserving indis' talking style and facial details. See how face texture stays rich, even as the audio changes. This keeps the person’s identity front and center.
Showcase 3 — Side-by-side quality check Qualitative Comparison Comparing with Person-Agnostic Methods Comparing with Person-Specific Methods. This clip highlights where mouth timing, style, and detail differ between methods. Look for sharper lips and more stable identity here.
Showcase 4 — More comparisons for fair testing Qualitative Comparison Comparing with Person-Agnostic Methods Comparing with Person-Specific Methods. You can see where other methods blur or lose style, and where PersonaTalk holds up. Pay attention to small face details through the sequence.
Showcase 5 — Multilingual Translation: English (Original) English (Original). This shows the base clip used for cross-language tests. It sets a fair point of reference for lip timing and style.
Showcase 6 — Multilingual Translation: Chinese Chinese. See how lip timing matches the new language while the speaker’s face still feels the same. Style stays strong across the change.
Tips for Best Results
- Use a clear reference video with good light and a steady face view.
- Use clean audio with low noise. Fewer echoes lead to better mouth shapes.
- Keep head movement moderate in the reference clip so the model can read details well.
