Technical Request for Browser-Based Voice Integration with Retell Hello Retell Support, We are implementing a real-time, browser-based voice interface for our internal legal support agent (“Andrew”), which is already fully configured as a Retell phone agent. We’ve deployed a front-end environment on Vercel and now need to connect the browser’s microphone stream directly to Retell’s real-time agent engine. We need clarification on the official Retell-supported method to establish a web voice session (WebRTC/WebSocket/SDK) without involving PSTN or SIP calling. Enable real-time streaming audio from the user’s browser microphone to our Retell agent, receiving streamed TTS audio responses, with low latency suitable for conversational use. Please advise on the correct Retell integration path for this browser-native voice agent.

I can assist in streaming browser microphone audio directly to your Retell agent and delivering real-time TTS responses with low latency, ideal for conversational use. I’ve implemented similar WebRTC/WebSocket setups for live voice agents. Could you clarify if you prefer a fully client-side solution or if a minimal backend relay is acceptable? @Richard
