Voice-Controlled Home Automation Bot

Objective

To design and implement a voice-controlled home automation system that controls devices like lights and fans using spoken commands.

Problem Statement

Traditional switches require manual operation. This project provides a hands-free solution using voice commands for home device control.

Tools & Technologies

• Python

• SpeechRecognition API

• PyAudio

• ROS (conceptual)

• Webots (conceptual simulation)

  🔌 Hardware Prerequisites

To use this system, your machine requires:

• Working Microphone: For capturing spoken voice commands.
• Audio Output (Speakers/Headphones): To listen to system responses.
• Stable Internet Connection: Required if the SpeechRecognition API routes requests to online speech engines.

System Architecture

Voice Input → Speech Recognition → Command Parser → Actuator Module → Device Control

Implementation

The system captures voice input using a microphone, converts speech to text, parses commands, and triggers corresponding actions for home devices. Device control is simulated using console output.

Results

The system successfully responds to voice commands such as:

• "Light on"
• "Light off"
• "Fan on"
• "Fan off"

Future Scope

• Integration with ROS publishers and subscribers
• Smart home simulation using Webots
• Hardware implementation using ESP32 or Arduino
