This project is a real-time AI-powered voice assistant designed to help tourists explore London, UK. It transcribes live speech, generates AI responses using OpenAI's GPT, and provides voice feedback using ElevenLabs.

🎯 Features

• Real-time speech-to-text transcription using AssemblyAI

• AI-generated responses powered by OpenAI's GPT-4o

• Text-to-speech voice output using ElevenLabs

• Interactive and conversational travel guide experience

🚀 How It Works

1️⃣ The assistant starts by greeting the user with a voice message.

2️⃣ It listens to the user's voice and transcribes it in real-time.

3️⃣ The query is sent to GPT-4o for a smart AI-generated response.

4️⃣ The assistant then speaks the response using ElevenLabs.

5️⃣ The loop continues, making it an interactive conversation! 🗣️
