Skip to main contentWhen designing a voice agent experience, the voice that your agents will speak in is a critical choice that will influence your customers’ experience.
Cartesia offers 500+ voices out-out-of-box, as well as the ability to clone your own voices.
Stable voices (best for voice agents)
For voice agents in production, we’ve found that more stable, realistic voices perform better than studio quality, emotive voices. From our testing, we think these are the top performing Voices for voice agents in Sonic 3:
- Male: Kiefer, Brandon
- Female: Katie, Jacqueline, Brooke
Emotive voices (best for AI characters)
Our latest model, Sonic 3, is very expressive with some voices like Tessa and Maya labeled as emotive in the playground, and respond well to emotion instructions.
If your use case requires more expressive speech (e.g. companion apps, game characters), then we suggest trying:
- Male: Kyle, Cory
- Female: Tessa, Ariana
We tag such voices as Emotive in our playground and you can see a full list here.
