What is ElevenLabs used for in a Bolna voice agent?
ElevenLabs is Bolna's default text-to-speech provider: it turns your agent's replies into natural speech, with a large voice library and voice cloning. Pick it when voice quality and a wide choice of voices matter, including custom cloned voices for your brand.
How do I set up ElevenLabs with Bolna?
- Optional: connect your own ElevenLabs account at platform.bolna.ai/auth/elevenlabs. You need this to use voices or clones from your own ElevenLabs account.
- Open your agent in Agent Studio and go to the Languages tab.
- In the Voice section, choose ElevenLabs as the provider and pick a model, for example
eleven_turbo_v2_5for low latency. - Pick a voice from the searchable list and preview it with your welcome message.
- Under Advanced settings, keep the buffer size around 250. Raise it to 350 to 400 if audio sounds choppy.
For models, settings and troubleshooting, see the ElevenLabs setup guide in the Bolna docs.
Which ElevenLabs models and languages does Bolna support?
| Model | Best for | Languages |
|---|---|---|
eleven_turbo_v2_5 | Low-latency English, recommended for production | English |
eleven_flash_v2_5 | Fastest time-to-first-audio, slightly lower quality | Not stated in the Bolna docs |
eleven_multilingual_v2 | Multilingual voices, selectable in the dashboard | Not stated in the Bolna docs |
eleven_v3_conversational | Most expressive | 74 |

A few voices do not render on eleven_v4_turbo and are left out of its voice list. They still work on the other models.
What can you build with ElevenLabs and Bolna?
A brand voice on every call. Clone your own voice once and use it across every agent in your workspace.
Indian-accented English support. Use Indian voices such as Anika (customer care) or Raju for support and sales calls in India.
English plus Indian languages. In a multilingual agent, use ElevenLabs for English and Sarvam for Hindi, each on its own language tab.
Expressive conversations. Use Eleven v3 or v4 Turbo for calls where tone matters, such as feedback or customer care.
