Hey,
i wonder if anybody has managed to set up a Matrix Voice (on a RPi) together with Rhasspy. Maybe you could share your setup in particular:
Have you got some tips for beginners, some further resources or tutorials, that you have used?
Thank you 
I have not, but please do share any experience, Iām currently working on this as well.
What Iām thinking so far is:
Iāll let you know if I get something to something usable. Please do the same, since Iām also pretty much just poking stuff with a stick, and seeing what happens at this point.
At the moment iām struggeling to get my mic and especially my speakers setup. The strange thing is, that if i select the Matrix Voice device in the config and press save, it restarts. After the restart however the default device is selected (which i donāt know which one this is).
A even bigger problem is that my external soundcard isnāt even listed in āAudioā. 
Have you got any experience with that?
From what I can see, the microphone will always say Default Device after you save, but the changes should still be made. For the mics, I selected:
Use arecord directly (ALSA)
hw:CARD=MATRIXIOSOUND,DEV=0: Direct hardware device without any conversions
Speaker worked for me when I plugged it into the audio jack.
Yes, that seems to work. Microphone and speaker (mini-jack) works, rhasspy sends MQTT to Home Assistant.
Now though, the RPi3B+ becomes unresponsive after a short while. The web interface works OK for a while, but testing the voice commands sort of freezes. And after a short while, even the SSH connection breaks.
@Carlos, do you have it (every component) running on a Raspberry Pi? And is it functional? If so, could you share which components you are using?
Hey @Aephir,
I havenāt tested much but my assistant was still running after a few hours of being on. Hereās a bullet list of what I have:
Maybe thatās it, Iām trying with an older Pi3B+. I have a 4GB RPi4 lying around, if unloading processing doesnāt work, I might try that. Thanks!
@Mondmonarch I havenāt really used any tutorials, mainly used the official docs. Are you still having issues? If so, I can try to find what Iāve used?
@Aephir at the moment iām short in time, but moving towards to the christmas vacation, iāll try to get it working 
But iām also using a Pi3B+, is that an issue?
No clue. I just know that my RPi3B+ seems to freeze, but I canāt say for certain if this is because Matrix/Rhasspy is too much, of because of something something else. Iāll do some testing once I have a bit more time.
But if it is a limitation of the Pi3, there is the option to send audio for processing somewhere else (remote HTTP server) for the heavy lifting.
Tried Rhasspy on Stretch on a Pi 3B+ and was having issues getting it to work. On the same Pi 3B+ with Buster though, the assistant worked with the ALSA microphone of MATRIXIO-SOUND card 2, device 0 selected in āSettingsā.
Weāre still not sure about the reliability but weāre working on a base guide for Rhasspy to be released soon which will hopefully help people get set up with it.
Best,
Samreen
This would be great. I think as a consequence of the snips.ai shutdown lotās of people are thinking about moving to rhasspy
Thank you very much in advance
Hello!
Here is the basic set up guide for Rhasspy. We need to test more and play around with it but it should hopefully help you get it up and running!
Best,
Team MATRIX
Thanks, @Samreen, Iāll give it a try. Still no (full) support for Buster then, I suppose? Any idea of the timeline (I know you guys are working on it, and Iām not trying to be pushy, just trying to figure out how much effort I should put into Strertch at this point )
And btw, you might want to link to this site (or this one for lite version) in the documentation, since your current link directs to a Buster download, while telling you to download Stretch.
Thank you for pointing that out! Weāve updated the docs to say latest Raspbian image.
We do support Buster fully! The only things that we are aware of that are having some issues on Buster is the MATRIX HAL microphone examples which we are working on. The MATRIX kernel modules and all other functionality work fully on Buster.
For Rhasspy, Raspbian Buster seems to work the best so that is the OS I would recommend for the guide.
Best,
Samreen
Iām having trouble detecting my sentences. Currently iām using a german assistant.
Iāve recorded the command of turning on the light and this was the outcome:
This is how i defined the sentence:
[Schalte das ] Licht an
[Set the]_____light on
(roughly translated)
I have also added the words:
And it seems like Pocketsphinx is understand nonsense:

Is there anything i have missed during the setup?
Thank you for your support 
Hi @Mondmonarch,
Are you using the wakeword/is it working?
It seems like it canāt hear you.
Did you make sure to select āarecord directlyā and the MATRIXIOSOUND direct hardware device for audio?
The setup is a bit sensitive right now so little differences in steps might affect the outcome. If you are using the wakeword, Iād recommend looking out for a line with ['arecord' '-q' '-r' '16000'...] in the logs as that line tells you what microphones are being selected in the -D parameter. They would have to be hw:CARD=MATRIXIOSOUND,DEV=0.
Let me know how it goes!
Best,
Samreen
Hi @Samreen
yes, i had the right settings selected. I was quite unhappy with the german version, so i switched to the english version. Everything is working fine now. I was even able to control my home assistant through node red ( WebSocket Events).
At first i tried to use Home Assistant Integration.
A visual feedback for the wakeword through the leds is the next thing on my todolist. Do you have any tips for me, on how to achieve this?
Iām also facing problems in changing the wakeword, i already failed with snowboy. Maybe on porcupine the jarvis model?
How can i place a custom wakewordfile in the corresponding directory? If anybody got an idea, Iām happy for any replies.
Thank you very much and merry christmas 
Hey @Mondmonarch,
I havenāt tried other wake word engines aside from Porcupine, but I know it has a few customs words to pick from here. Once downloaded, you can add the file inside the porcupine folder located in ~/.config/rhasspy
I forgot the exact path, but I think it should be inside the profile youāre using (en, es, etcā¦). You can then select the wake word file from Rhasspyās web GUI.
If you havenāt already, you should take a look at the Rhasspyās wake word docs.
For listening to wake word events, I submitted a feature request on GitHub that the author of Rhasspy is considering. However, they posted a workaround in the meantime.
Happy Holidays! 
Hey @Carlos
My Matrix Voice now turns blue, if the wakeword is detected. I have setup an mqtt broker on my Raspberry Pi and linked the docker container with Rhasspy (runs on the same pi) to this broker.
Furthermore I wrote a Python programm, that connects to the mqtt broker aswell and subscribes to the rhasspy/en/transition/SnowboyWakeListener topic, as Iām using Snowboy to detect the wakeword. As Iāve only learned the Python basics, this program could probably be improved 
To start the program on boot, Iāve created a Unit File in SYSTEMD.
)Maybe someone has got an advice, on how to achieve this goal.
I can also share my code, if anyone is interested.
Happy holidays 
Nice!
I think you can do something like this for the LED sequence you want. I donāt have a Pi near me so youāre gonna have to make some minor edits to render it on your MATRIX device.
from math import trunc
from time import sleep
ledLength = 18
everloopImage = ["black" for i in range(ledLength)]
for i in range(trunc(ledLength/2)):
everloopImage[i] = "blue"
# matrix.led.set(everloopImage)
sleep(1)
everloopImage[ledLength-1-i] = "blue"
# matrix.led.set(everloopImage)
sleep(1)
