JARVIS - Just A Rather Very Intelligent System

A Python-based voice assistant that can execute commands, open applications, and answer questions using Google's Gemini AI.

Features

✨ Voice Commands - Control your computer with natural speech 🎤 Wake Word Detection - Activate with "Hey Jarvis" or always-listening mode 🤖 AI-Powered - Uses Google Gemini for intelligent responses 🚀 Quick Actions - Open apps, browsers, and system tools instantly ⏰ Time & Date - Get current time and date information 🔍 Web Search - Search the web with voice commands 💻 System Control - Shutdown, restart, and get system information 📱 18+ Applications - Open popular apps with simple voice commands

Installation

1. Clone the repository:

git clone https://github.com/KrishnaSrinivas-24/JARVIS.git
cd JARVIS

2. Install dependencies:

pip install -r requirements.txt

3. Set up your Google Gemini API key:
   • Get your API key from Google AI Studio
   • Replace "Paste your API Here" in jarvis.py with your actual API key

Usage

Run JARVIS:

python jarvis.py

You'll be prompted to choose a listening mode:

• Option 1: Wake Word Mode - Say "Hey Jarvis" or "Jarvis" to activate
• Option 2: Always Listening Mode - No wake word needed (default)

Wake Word Mode

When using wake word mode:

1. Wait for the prompt: Waiting for wake word...
2. Say "Hey Jarvis" or "Jarvis"
3. JARVIS will respond: "Yes? How can I help you?"
4. Give your command
5. Repeat for each command

Benefits:

• Privacy-friendly - only listens when activated
• Saves battery on laptops
• Reduces false positives in noisy environments

Recent Improvements

Wake Word Detection (Issue #2)

• ✅ Added optional wake word mode with "Hey Jarvis" or "Jarvis" activation
• ✅ User can choose between wake word mode and always-on mode at startup
• ✅ Improved privacy - only listens when wake word is detected
• ✅ Better battery efficiency for laptops
• ✅ Reduced false positives in noisy environments

Continuous Listening Optimization (Issue #1)

• ✅ Removed recursive restart after unknown responses
• ✅ Added proper error handling for all speech recognition exceptions
• ✅ Implemented timeout and phrase limits to prevent hanging
• ✅ Added ambient noise adjustment for better recognition
• ✅ Continuous loop without restart delays

Benefits:

• No more infinite loops on recognition errors
• Faster response time between commands
• Better error recovery
• Smoother user experience
• Privacy-friendly wake word option

Requirements

• Python 3.7+
• Microphone access
• Internet connection (for speech recognition and Gemini AI)
• Windows OS (for application shortcuts)
