Build me a modern voice assistant web app called Lisa.

I want a clean React front end and a FastAPI backend that lets people talk to the assistant with their microphone, see the conversation in a chat window, and hear spoken replies back. It should support guest mode with local chat history, and if the user signs in with Supabase, their chats should be saved and carried across devices.

Please make it smart enough to answer questions using an AI model, with live web search when needed, speech to text for the user’s voice, text to speech for Lisa’s voice, and browser geolocation so it can respond with local context when helpful. I also want a simple music feature that can play YouTube links. Use a modern, polished UI that feels like a real product and is easy to use on desktop and mobile.

If you need current docs or API details for the services, look them up online and wire everything together so it works end to end.
