\ud83c\udfaf Project<\/strong> Objective<\/strong><\/h2>\n\n\n\n

To create a Python-based voice-controlled assistant<\/strong> that listens to commands, performs actions (like searching the web or opening apps), and speaks responses aloud.<\/p>\n\n\n\n

\n\n\n\n

\ud83e\udde9 1. What You\u2019ll Learn<\/strong><\/h2>\n\n\n\n
    \n
  • \ud83c\udfa4 Capturing voice input using speech_recognition<\/code><\/li>\n\n\n\n
  • \ud83d\udd0a Making Python speak with pyttsx3<\/code><\/li>\n\n\n\n
  • \ud83c\udf10 Performing tasks like opening YouTube, searching Google, checking time, etc.<\/li>\n\n\n\n
  • \u2699\ufe0f Handling multiple commands with simple AI logic<\/li>\n<\/ul>\n\n\n\n
    \n\n\n\n

    \u2699\ufe0f 2. Required Libraries<\/strong><\/h2>\n\n\n\n

    We\u2019ll auto-install them within the code \ud83d\udc47<\/p>\n\n\n\n
