If you're diving into voice-enabled applications for Google Home or Alexa, this book is a great starting point. The explanations are clear, and it covers Dialogflow and Alexa Skills Kit well. I found the step-by-step guides super helpful when building my first voice app.

However, like some reviewers mentioned, it's very software-focused. I was hoping for more on integrating VUI with existing embedded systems or hardware components. That part felt a bit light.

The projects are practical and well-explained, making complex concepts accessible. The Amazon Echo examples worked flawlessly when I tested them. But if you need hardware integration tips, you might need to supplement with other resources.

Overall, it delivers what it promises for software development. Just know going in that it's not the right pick if you're looking for hardware-focused VUI implementation.
