MetaMind-Chatbot: PDF Voice Chatbot

MetaMind is a Streamlit-based application that enables users to interact with PDFs using text or voice queries. It processes PDFs, extracts their content, and allows users to ask questions about the documents using an AI-powered chatbot.

Features

• PDF Processing: Loads and indexes PDFs from the Data/ folder.
• AI-powered Q&A: Uses LangChain and Ollama to retrieve relevant document chunks and generate answers.
• Voice Input Support: Converts speech to text using SpeechRecognition.
• Text-to-Speech (TTS): Converts chatbot responses into speech using gTTS.
• Fast Retrieval: Uses FAISS for efficient document search.
