Where to find itAssistantTechnical configurationVoice tuning
Go to Technical configuration. The controls change depending on the voice.
Voice tuning
| Control | What it changes |
|---|---|
| Speed | Sets how fast it talks. 1.0 is normal, and the control goes from 0.7 to 1.2. |
| Stability | A high value keeps the voice more consistent. A low one allows more variation and expressiveness. |
| Similarity boost | Sets how closely the result matches the original voice. |
| Style | Sets how strongly the voice’s own style comes through. 0 is neutral. |
Expressive voice
Some voices show Expressive voice instead of the controls above. Try Off, Texture, or Texture + Emotion and listen for the one that fits best. Only available in English and Spanish.
Good to know
To change the voice speed, use this control. Writing “speak more slowly” in the instructions doesn’t change it.
Test it
Change one value at a time, save, and listen to a test with a price, a date, and a name.
