How realistic do the voices sound on a phone call?

Most callers can't tell the agent is AI. Pacing, intonation, emotional tone, and even small things like breath sounds are realistic. The voice adapts based on the conversation — slower for complex info, warmer when empathy's needed.

Can I clone my own voice?

Yes. Upload audio samples and ElevenLabs creates a custom voice that sounds like the source. Most teams clone their founder, CEO, or a senior receptionist for brand consistency.

What languages are supported?

30+ languages with native-quality pronunciation — English, Spanish, French, German, Portuguese, Mandarin, Japanese, and more. Multilingual flows let the agent switch based on what the caller speaks.

Can the same voice be used across multiple locations or agents?

Yes. Once a voice is set up — stock or custom — it can power every AI agent across every location for brand consistency.
