Vikash Kumar Mehta submitted a project on developing a voice assistant named JARVIS using Python. JARVIS can perform tasks like playing music, conducting Wikipedia searches, opening websites and apps. It uses libraries like Pyttsx3 for text-to-speech, speech recognition for voice input, webbrowser to control browsers, and OS and Pywhatkit for system interactions and WhatsApp messaging. The voice assistant technology offers convenience to users while accessing unlimited online knowledge, though smart speakers also create new marketing channels for businesses.
