Virtual Assistant using Python, NLP & LLMs 🤖

Overview

This project is a Python-powered virtual assistant that combines Natural Language Processing (NLP) and Large Language Models (LLMs) to provide intelligent, context-aware conversational support and task execution.

Built as a college/final-year capstone, the assistant can understand spoken or typed input, generate responses using LLMs, and perform actions like web search, reminders, weather lookup, and more.

🎯 Key Features

• Natural Language Conversation: Supports voice/text input using speech recognition and text-to-speech.
• LLM Integration: Utilizes models like GPT‑4, LLaMA, or OpenAI API for response generation.

📥 Installation

1. Clone the repository bash git clone https://github.com/VASU-GATTE/Virtual_Assistant_using_Python-NLP_and_LLMs.git cd Virtual_Assistant_using_Python-NLP_and_LLMs

2. (Optional) Set up Python virtual environment

   python3 -m venv venv
   source venv/bin/activate  # Windows: venv\Scripts\activate

3. Install dependencies

   pip install -r requirements.txt

4. Configure API keys

   • Create a .env file or update config.py with keys such as:

     • OPENAI_API_KEY
     • WEATHER_API_KEY
     • Optional: other service keys

🚀 Usage

To launch the assistant:

python mod.py

or

python mod.py

Then:

• Use voice input (speak when prompted) or type text commands
• The assistant will process your query via NLP/LLM and respond or act
• Sure! Here's the updated section with example commands tailored to your college context:

---

🗣️ Example Commands (College-related)

• "What is the name of my college?"
• "Where is DVR & Dr. HS MIC College of Technology located?"
• "Who is the principal of my college?"
• "Tell me about the CSE department in my college"
• "When does the next semester start?"
• "What are the upcoming college events?"
• "Show me the academic calendar"
• "Open the college website"
