+# Tourist Assistant
+
+An interactive voice-enabled tourist guide that provides information about cities, landmarks, and destinations worldwide. This application uses OpenAI's GPT models for text generation and speech features for a natural conversation experience, along with RAG capabilities and Google Places API integration for real-time attraction information.

+
+## Features
+
+- Text-based chat interface for asking questions about tourist destinations
+- Voice input capability through microphone recording
+- Audio responses using OpenAI's text-to-speech technology
+- Clean, responsive user interface with Gradio
+- RAG (Retrieval-Augmented Generation) system using PDF knowledge base
+- Google Places API integration for real-time information about attractions
+- Set current location for contextual queries
+- Quick access to nearby attractions information
+
+## Requirements
+
+- Python 3.9+
+- OpenAI API key
+- Google Places API key (optional, for location search features)
+
+## Installation
+
+1. Clone this repository
+2. Install the required dependencies:
+   ```
+   pip install -r requirements.txt
+   ```
+3. Create a `.env` file in the project directory with your API keys:
+   ```
+   OPENAI_API_KEY=your_openai_api_key_here
+   GOOGLE_PLACES_API_KEY=your_google_places_api_key_here
+   ```
+4. (Optional) Add PDF files to the `knowledge-base/` directory to enhance the assistant's knowledge about specific locations
+
+## Running the Application
+
+Start the application by running:
+
+```bash
+python tourist-assistant.py
+```
+
+The interface will automatically open in your default web browser. If it doesn't, navigate to the URL shown in the terminal (typically http://127.0.0.1:7860/).

+6. Use the "Refresh Knowledge Base" button to reload PDFs in the knowledge-base directory
+7. Use the "Clear" button to start a new conversation
+
+## Technologies Used
+
+- OpenAI GPT-4o Mini for chat completions
+- OpenAI Whisper for speech-to-text
+- OpenAI TTS for text-to-speech
+- Langchain for RAG implementation
+- FAISS for vector storage
+- Google Places API for location-based attraction information
+- Gradio for the web interface
+- pydub for audio processing
