About Jambonz

What Jambonz offers

- Speech vendor layer with per-app defaults and fallback, including Deepgram STT and Voice Agent
- Deployment in your VPC or on-prem, or hosted on jambonz.cloud
How Jambonz works with Deepgram
Deepgram is a built-in speech-to-text vendor in Jambonz, and its llm verb connects a live phone call straight to Deepgram Voice Agent with nothing more than a Deepgram API key.
