Who this is for
You want to choose how Scarlett sounds. Her standard voice is British and works out of the box — you don't have to change anything.
Time: 3 minutes. You'll need: to be the owner or a manager.
Before you start
- Train Scarlett on your business — the voice is what everything she knows is said in.
This page used to let you pick the AI models behind Scarlett too. Those choices asked a plumber to pick infrastructure, so we made them for you. What's left is what's genuinely yours: the voice and how fast she speaks.
On phone calls Scarlett currently speaks in her standard British voice. The voice you pick here is the one you hear under Test agent and when you talk to Scarlett in the app.
Steps

1. Pick a voice
On Train Scarlett → Voice, the voices are grouped British and Other accents. Press the play button on a tile to hear a sample.
2. Select it
Tap the tile to select it — there's nothing else to save. The tile shows Selected.
3. Set how fast she speaks
Drag How fast she speaks between Slower and Quicker. Slower is easier to follow on a bad line or for an older caller; quicker gets to the point for trade callers who ring a lot. It saves when you let go.
Verify it worked
The voice you picked shows Selected, and under Test agent she speaks in it.
Troubleshooting
"Voices unavailable." The voice service couldn't be reached just then. Try again in a moment.
My voice change didn't affect a phone call. That's expected — on phone calls Scarlett uses her standard British voice.
