The Blockchain Hotel Voice Assistant

Overview

This project demonstrates a real-time voice assistant API that captures user actions and transforms them into blockchain interactions. As a demo use case, we use an on-chain reservation system for "The Blockchain Hotel," where reservations are modeled as NFTs. The voice assistant queries the user for check-in and check-out dates, checks if the corresponding NFTs are not minted, and if available, initiates a mint transaction.

Features

• Real-time voice assistant API integration
• On-chain reservation system using NFTs
• Voice-based interaction for booking hotel rooms
• Checks availability of rooms by querying the blockchain
• Mints NFTs for reservations if available

];

Running the Project

1. Start the local blockchain:

   yarn chain

2. Deploy the smart contracts to the desired network (replace xxx with the network name, e.g., baseSepolia):

   yarn deploy --network xxx

3. Start the front-end application:

   yarn start

4. Start the real-time voice activity detection (VAD) service:

   yarn relay

Usage

1. The voice assistant will greet you and ask for your check-in and check-out dates.
2. Provide the dates, and the assistant will check the availability by querying the blockchain.
3. If the dates are available, the assistant will initiate a mint transaction to reserve the room as an NFT.
