🎙️ Voice Assistant (Python)

Problem Statement

In today’s fast-paced digital world, users want hands-free, intelligent assistants that can understand natural language and perform daily tasks efficiently—similar to Alexa, Google Assistant, or Siri.

Solution

This project builds an Advanced Voice Assistant capable of:

• Understanding spoken language
• Interpreting user intent using NLP
• Performing real-world tasks autonomously
• Integrating with third-party APIs for extended functionality

This assistant is designed as a modular, scalable system, not just a basic speech-to-text script.
