What is ElevenLabs Scribe used for in a Bolna voice agent?
ElevenLabs Scribe turns the caller's speech into text for your Bolna agent, using the scribe_v2_realtime model with about 150ms latency across 90 languages. It returns word-level timestamps, detects the spoken language automatically and decides when a caller has finished with VAD-based endpointing. It is also on Bolna's preferred model list, so it fits inside the flat rate.
How do I set up ElevenLabs Scribe with Bolna?
- Open your agent at platform.bolna.ai and go to the Languages tab.
- Under Transcription, set Provider to ElevenLabs and Model to
scribe_v2_realtime. - Pick the caller's language.
- Add up to 50 brand or product terms in Keywords. Weights are dropped.
- On the Engine tab, adjust Endpointing if the agent cuts callers off or waits too long. Scribe accepts silence thresholds from 0.3 to 3.0 seconds.
In the API, set provider to elevenlabs and model to scribe_v2_realtime on tools_config.transcriber. See the ElevenLabs transcriber guide in the Bolna docs.
