Overview
An AI voice assistant that takes phone orders for a pizza restaurant autonomously, using VAPI for voice-call orchestration, the Anthropic Claude API for conversation, and ElevenLabs for voice synthesis.
What was built
- Retrieval-Augmented Generation (RAG) so the assistant answers from the restaurant's real menu instead of inventing items.
- Context tracking and continuous validation checks to keep order details accurate throughout each call.
- Prompt engineering to control tone and conversation flow, keeping the interaction natural end to end.
Result
A working autonomous phone-ordering flow — directly demonstrates the "AI Voice Agents" service Vectia offers to small businesses with high call volume.
TODO before publishing: confirm whether this was run with a real restaurant or is a standalone demo, add a call recording/transcript excerpt if shareable, and add a measurable result (e.g. orders handled, accuracy rate) if available.
