I have just received my Matrix Creator.
I work on a similar project.
I was believed that the mics will be recognized by the Pi3 as an audio record / input device on the alsamixerr so i will be able to use it with any programs.
You can have a look on this project who ha already implemented Snowboy https://github.com/alexylem/jarvis/wiki
It's in french but the guy speak English and the interface and settings have been built in English. It handles Google, Bing, snowboy, espeak, pico, .... It works pretty good but needs good microphone support for Pi to handle ambiance sound,(TV, news channel,...) So it should be able to know when the user finish to say his command
For the moment i have just tried micarray_recorder demo to "listen" the sound quality which is pretty good.
I compared with alexa demo with matrix creator so i suppose that it's possibe combine the 8 mics to one wav file instead of 8 seperate raw files?
@ben and @sysctl can we combine our efforts to make it work?
A always listening system to catch the hotword then to tell a command for home automation, questions, ...
Thanks a lot.. hope i can contribute for Matrix Creator
