Turn Your Raspberry Pi Into An Amazon Echo
Smart speaker assistants utilize technology for our home convenience and have rightly become a core feature in most households, centralizing control of various devices and making them far easier to use. In a past session, we turned a Raspberry Pi into a DIY Google Home-style assistant, but in this workshop, we will continue that pursuit by transforming a Pi into a customizable smart speaker modelled on the other prominent brand in the market: the Amazon Echo.
We’ll show you how to incorporate Amazon’s Alexa APIs and set up voice controls for our device, allowing for easy sync with home technology and companion apps.
