How do I change an avatar's voice in Synthesia?
In the Synthesia editor, click the speaker pill above the script box for that scene, open the Voice Selection Menu, and pick a new voice or language from the 1,000+ available (or your own voice clone). Voice and avatar are separate, so changing the voice doesn't change the face. Apply per scene or across the whole video.
Why — the first-principles explanation
The reason changing a voice is quick is that Synthesia keeps the avatar (the face) and the voice as two independent settings. A scene is really 'this visual + this face + this script, spoken in this voice.' Because the voice is its own slot, swapping it doesn't touch anything else, the face, script, and layout all stay put.
That design is why the control lives on the speaker pill above each script box. Each speaking part in a scene points at a chosen voice, and clicking that pill opens the Voice Selection Menu, the single place where the voice is decided. From there you can pick any of the 1,000+ stock voices, switch languages, or select your own voice clone if you've made one.
Because voice is per-speaker and per-scene, you get precise control: change just one scene's voice, or set the same voice across every scene for consistency. This is also how you'd fix a mismatch, say your avatar was speaking in a default voice and you want a specific accent or gender instead.
The key mental model: you're not re-recording anything, you're re-selecting. The script stays as text; only the voice that reads it changes. Hit re-render and the same avatar now speaks your script in the new voice or language, which is exactly what makes translating or re-voicing a finished video so fast.
An example that makes it click
Think of a karaoke machine where the lyrics on screen stay the same, but you can swap who's singing them. The words (your script) don't change; you just tap a menu and pick a different singer, or the same song in another language. The dancer on stage (your avatar) keeps dancing exactly as before.
So if you decide the narration should sound British instead of American, you don't rewrite anything or refilm the dancer, you just choose a new voice from the list, and the same performer now 'sings' your lines in that voice.

How do you change an avatar's voice in Synthesia? It's a quick swap, because Synthesia keeps the face and the voice as two separate settings. So changing the voice never changes the avatar. Here's exactly how. Open your project and go to the scene you want to change. Above the script box, you'll see the speaker pill, that's the voice control for that part. Click it, and the Voice Selection Menu opens. This is the one place where the voice is decided. From here you can browse over a thousand voices, filter by language, accent, or gender, or pick your own voice clone if you've made one. Choose the new voice, and that speaker now uses it. You can do this scene by scene, or set the same voice across the whole video for consistency. The key idea: you're not re-recording anything, you're just re-selecting. The script stays as text, only the voice reading it changes. Re-render, and the same avatar speaks your script in the new voice or language.
