AI-powered voice gateway replacing hold music with intelligent conversation

AI Receptionist Voice Gateway

Built With

Twilio, Deepgram, Claude, ElevenLabs, and Supabase in one real-time pipeline

<1.5s

End-to-end voice latency

About

An AI receptionist that handles inbound calls with lead qualification, FAQ responses, scheduling, and message-taking. Sub-1.5s latency with streaming audio.

The Challenge

Traditional phone systems fail modern businesses

Customers calling in were met with frustrating IVR menus, long hold times, and missed opportunities for connection.

After-hours calls went to voicemail, leads went cold, and the team spent hours returning calls instead of closing deals.

The Solution

Streaming architecture for natural conversation

The voice gateway streams audio through Deepgram for real-time transcription, processes intent with Claude, and responds via ElevenLabs text-to-speech.

Barge-in detection allows callers to interrupt naturally. Graceful fallbacks ensure every call gets handled, whether by AI or voicemail.
