About Eleven Voice Design
Eleven Voice Design creates a new synthetic voice from a written description and returns three takes of it speaking your sample text.
Describe age, gender, accent, tone, pacing, and character, such as "a raspy older sea captain with a warm Scottish accent, slow and amused", and each run gives three distinct interpretations to choose from. It suits casting character voices for games and animation, narrators for a brand, and voices for synthetic speech data without recording anyone.
| Metric | Value |
|---|---|
| Outputs | 3 previews per run |
| Multilingual | Yes, 70+ languages |
