That is absolute correct, you only need a client to actually respond to that intent 
How to do that, is more a thing of snips, https://snips.ai/
They have a discord channel as well, with a lively chat
For Home Assistant integration, I advise you to check to component Snips.
On the discord of snips, there is also a home-assistant channel

Just a little question about controller a light with Matrix ,Snips ,HOME ASSISTANT. Should I need a special light bulb(bluetooth,zwave ,zigbeeâŚ) or just a Ordinary lamp?
If an ordinary lamp ,how to connect it with the home assistant? Need to Re-wiring ?
Well, you need some sort of connectivity in your lamp.
This can be a wifi light bulb or you can change your switch to a smart switch of sort (if you google you will find tons of options like https://getden.co.uk/ or SonOff and you could use all sorts of 433hz devices, just too many to list all of them here 
) No need to rewire though, in the majority of cases you just replace some old part with a connected one or put a device in between the switch and the bulb
Thanks for your answer. You said this can be a wifi light bulb. So it also could be a Zigbee light bulb or Z-wave or even a bluetooth light bulb? Just connect this light with Home assistant and matrix .Right?
Yes, but you should make sure that you first can control your light within Home Assistant.
I mean without any voice control.
The forum for Home Assistant is also very alive, you can find a lot of help there.
After that, you need to add voice control to Home Assistant, i.e. Snips.
The input for the voice control (a.k.a. Microphone) can then be the Matrix Voice or Creator.
So âJust connect this light with Home assistant and matrixâ is too simply said.
Thanks for your answer. Iâd like followed your full steps.
But after I run sudo apt install matrixio-kernel-modules
It show the error message

Do you know the solution?
And I did sudo apt-key adv --keyserver pgp.mit.edu --recv-keys D4F50CDCA10A2849
OR
sudo apt-key adv --keyserver pgp.surfnet.nl --recv-keys D4F50CDCA10A2849
But it showed gpg: keyserver receive failed: No data
Is there other server?
I do not know, those were working fine beforeâŚ
Iâve removed DUMMY from matrix-mics.conf ,but why it still show these errors?

what is your output of arecord -l
snips-watch shows only logs, so when nothing is to be done no lines will be shown
The output of arecord -l

Microphones from Matrix Voice worked with Snips as long as I did first âapt-get upgradeâ on Raspberry. After that update, Matrix Voice did not work any more.
Hi @milode,
Please, take a look to this Hackster post MATRIX Voice and MATRIX Creator Running Snips.ai
Are LEDs working? or is just the mics?
Ultimately you could use this guide - Hardware Test: Microphones , to check for hardware issues.
Let us know the results

Hi @yoelrc88,
thanks a lot for reply.
At the moment I have stopped working with Matrix Voice, because the audio output of Matrix Voice does not work either. I have the impression Matrix Voice isnât really finished yet.
I am currently trying ReSpeaker 2-Mic/4-Mic/6-Mic Pi HAT from Seeed. The microphones and the audio output work here without problems with snips.
Maybe Iâll try the Matrix Voice again later if it should work stable.
The description on Hackster âMATRIX Voice and MATRIX Creator Running Snips.aiâ seems to be very similar to the description of Romkabouter.
Unfortunately I wasted a lot of time with Matrix Voice, in contrast to that ReSpeaker works right away for my purposes.
Hi @milode,
Thanks for the feedback, its always welcomed.
You shouldnât have any issues with the microphones with Snips, if you have, please post the error and we for sure help you. The output in the kernel modules is currently being worked on due to some bugs, so its not ready yet. We are on that and should be fixed in 1 or 2 weeks max. In the meantime you can use the 3.5mm audio output from the Pi.
Let us know if you need help with the microphones.
-Yoel
Hi Yoel,
thanks for reply.
Iâm curious to see if audio output works in two weeks.
if this realy works, I will try Matrix Voice again
Please include an example app as well!
