Build voice-based LLM apps in minutes
Vocode is an open source library that makes it easy to build voice-based LLM apps. Using Vocode, you can build real-time streaming conversations with LLMs and deploy them to phone calls, Zoom meetings, and more. You can also build personal assistants or apps like voice-based chess. Vocode provides easy abstractions and integrations so that everything you need is in a single library.
We're actively looking for community maintainers, so please reach out if interested!
⭐️ Features
- 🗣 Spin up a conversation with your system audio
- ➡️ 📞 Set up a phone number that responds with a LLM-based agent
- 📞 ➡️ Send out phone calls from your phone number managed by an LLM-based agent
- 🧑💻 Dial into a Zoom call
- 🤖 Use an outbound call to a real phone number in a Langchain agent
- Out of the box integrations with:
- Transcription services, including:
- LLMs, including:
- Synthesis services, including:
