📋 Overview
Phone AI is a proof of concept for voice AI services, built under Big Boulder Studios. AI agents handle incoming business calls — answering questions, booking appointments, taking messages, and routing urgent calls.
💡 Context
Small businesses miss a lot of incoming calls — and every missed call is a potential lost customer. Traditional solutions like hiring a receptionist or outsourcing to a call center are expensive. Phone AI provides an AI agent that picks up every call, available 24/7.
🛠 Tech Stack
🧠 Technical Architecture
The voice pipeline is built for low latency — the delay between a caller finishing their sentence and the AI responding needs to feel conversational, not robotic.
End-to-end latency in a voice AI pipeline compounds fast: STT transcription + LLM inference + TTS synthesis + telephony buffering. Each step adds 200-500ms, easily resulting in 1-2 second pauses that feel awkward and break conversational flow.
Real-time streaming at every stage: STT streams partial transcripts, the LLM streams token-by-token responses, and TTS begins synthesis on the first sentence before the full response is generated. WebSocket connections stay warm between turns. The result is sub-second response times that feel like talking to a real person.
🎯 Role
Built under Big Boulder Studios with Nino. Developed the voice AI system and client onboarding workflow.
✨ Key Highlights
- Sub-second response latency via end-to-end streaming architecture
- Custom-trained per business — not a generic chatbot
- 24/7 availability at a fraction of hiring a human receptionist
- Natural conversational voice — callers often don't realize it's AI
- Handles booking, FAQs, message-taking, and intelligent call routing
