01.
The Problem

Dental clinics face high call volumes for routine tasks like booking appointments and answering FAQs, often leading to missed calls or administrative bottlenecks. Patients expect instant, 24/7 availability which human receptionists cannot provide.

I built a voice pipeline using Python and Pipecat. The system orchestrates OpenAI's GPT-4o for conversational intelligence, Cartesia for ultra-realistic TTS, and Silero VAD for seamless turn-taking. I implemented a RAG system using ChromaDB to retrieve clinic-specific knowledge (prices, policies) and integrated the Google Calendar API for real-time slot checking and booking. A WebSocket server handles the bi-directional audio streams.

The result is a fully autonomous voice agent that successfully handles complex scheduling dialogues, reduces administrative load, and provides a warm, human-like interaction experience for patients.
