What is that?
The Google AIY Voice Kit is a bundle of some hardware components along with an SDK to build your own voice assistant, similar to a Google Home.
First, it was released as a special version of the MagPi magazine issue #57. Later, because of the high demand, it got released as a stand-alone product.
What is included?
Apart from the Raspberry Pi, everything needed to build a voice assistant is included.

So the package includes:
- The voice HAT (a board to attach at the top of the Raspberry which acts as control unit and soundcard)
- A stereo microphone
- A speaker
- A LED button
- The cables to connect all of this
- A cardboard box as housing for all of this
- A manual
What else will be needed:
- A Raspberry Pi 3 (some other models are supported as well)
- A micro SD card
Setting it up
There is a very detailed manual included in the box with step by step instructions on setting up the hardware, the software and the account needed for the AI backend at Google.

The only issue I had was that the button included in the package was a different one compared to the one shown in the manual. So I had to play around with it a bit and check for some references online. Oh, before I forget, there is no soldering needed at all. Everything is set up with just plug connections.

After everything was set up, the voice assistant simply was working...
What does it do?
After everything is set up, the included demos can be executed. There are different versions, with button support and voice activation or just with the button activation.
Means, the assistant can be triggered by pressing the button or the "OK Google" voice command. After that simply ask something or give a command and the assistant will react to it. All in all, it works quite good and very similar to a real Google Home.

The microphone is extremely good and will understand spoken commands or the keyword even at a very large distance.
Just something to note here, it is NOT a Google Home. It's just the voice assist part of that. So it will not integrate into the Google Home network like other devices and can't cast media to a Chromecast connected with that network. On the other side, Google is constantly updating the SDK and adding features ... One of the latest updates also brought support for more languages than just English. Other features might follow.
The Google AIY Voice Kit is a great starter to get into the development of speech recognition applications. It is meant to be a starting point and Google forces the "Makers" to go further and develop their own tools and applications with it. That's also what they try to show with their slogan "Made by you with Google" and that is exactly what I have done already ...
But more on that in future article ;)
Google also released another Kit by now, the Google AIY Vision Kit which steps into the direction of image recognition. Looking forward to playing around with that as well at some point.
To me, the project is a great addition to everyone who wants to play around with some development skills. It's a great experience to bring some software development into the real world with some physical components, which makes playing around with all around the Raspberry Pi so exciting to me.
