What it does

Voiceblender provides a programmable voice platform for custom voice AI integrations, allowing founders to control SIP and WebRTC calls, mix multi-party audio, record conversations, and integrate with various AI agents through a REST API, webhooks, and WebSocket event stream.

When to use it

•When building a custom voice-controlled application that requires programmable call control and AI integration
•When needing to mix and record multi-party audio conversations in real-time
•When integrating with specific AI agents like ElevenLabs, VAPI, Pipecat, or Deepgram for advanced voice functionalities

Ready-to-paste prompt

curl -X POST -H 'Content-Type: application/json' -d '{"caller": "sip:user1@domain.com", "callee": "sip:user2@domain.com"}' http://localhost:8080/calls

Heads up: Make sure to obtain the necessary API keys for the AI agents you want to integrate with, such as ElevenLabs or Deepgram, as these are required for voiceblender to function correctly
