Tim Spann shows how to take off the shelf hardware and build a voice-activated workflow:
Using a Raspberry Pi 3 with Google AIY Voice Kit is an easy way to control data flows in an organization.
The AIY Voice Kit is a good way to prototype voice ingestion. It is not perfect, but for low-end, inexpensive hardware, it is a good solution for those who speak clearly and are willing to repeat a phrase a few times for activation.
I was able to easily add a word for it to react to. I also have it waiting for someone to press the button to activate it.
It seems like a fun DIY project.
