An Automation Using Alexa Raspberry Pi

Overview

This project aims to create a voice-enabled smart speaker prototype using Raspberry Pi, integrating custom voice assistance functionalities. The goal is to develop a versatile automation solution that leverages Raspberry Pi's capabilities for voice interaction.

Virtual assistants are a software that understands verbal commands and completes task assigned by clients.In existing system of virtual assistance there several virtual assistance in market by using artificial intelligence technology. Such as Microsoft Cortana for windows, Siri for iOS, etc. In this project we are suing python programming language because offers a good major library. Virtual assistants can provide several services which includes,

1. • Showing weather condition.
2. • Gives latest news.
3. • Turn on/off light.
4. • Showing datetime, Telling jokes.
5. • Searching on Wikipedia ,etc.

Features

• Voice control: Interact with the smart speaker using natural language commands.
• Custom voice assistance: Implement custom voice assistance functionalities tailored to specific needs.
• Extensibility: Extend functionality through custom scripts and integrations.

Hardware Requirements

• Raspberry Pi (Model 3 or higher recommended)
• Microphone (USB or 3.5mm jack)
• Speaker (3.5mm jack or HDMI audio output)
• Internet connection (Wi-Fi or Ethernet)

Software Requirements
