AI Voice Agent

A Python-based voice assistant that listens to user commands, performs system tasks, and uses a LangChain tool-calling agent for intelligent responses.

Features

• Voice input using microphone
• Text-to-speech response
• Open websites by voice
• Open Windows applications
• Tell current time
• AI responses using OpenAI via LangChain
• Tool calling support (search, wiki, save)

How It Works

1. User speaks through microphone
2. Speech is converted to text
3. System checks for:
   • Website commands
   • System commands
4. If no system command is found:
   • Query is sent to LangChain agent
5. Agent processes the query using tools
6. Response is spoken back to the user
