The problem
Inbound calls pile up. Leads sit uncontacted for hours because nobody is free to call them back. The calls that do get answered follow a predictable script almost every time — qualify the lead, ask a few questions, book the appointment, hand off to the right person. The structure is always the same, but it still needs a human to run it. That is the gap this was built to close.
The approach
- Built an end-to-end voice AI pipeline for both inbound and outbound calling, handling the full conversation from greeting to resolution
- The agent greets the caller, asks qualifying questions based on the configured call flow, books appointments against live calendar availability, and routes to a human only when the conversation goes outside what it can confidently handle
- Deepgram handles speech-to-text for low-latency transcription, GPT-4o runs the conversation logic with a custom prompt and function-calling setup, and ElevenLabs handles natural-sounding text-to-speech
- End-to-end latency from speech in to speech out stays under one second throughout the call
The result
Live calls handled end to end with no human required. Lead qualification and appointment booking happening automatically around the clock. Sub-second response latency keeping conversations feeling natural. The system has not missed a call or failed mid-conversation since it went live.
