Wake Word not detected

Archive - Mycroft Project This category is being retired - Support
1

I just set up Mycroft via DietPi on my Raspberry Pi 4. I’m using Blue Snowball as microphone and normal 3.5mm speakers. I can’t get Mycroft to detect the default wake words (“Hey Mycroft” nor “Wake up”). I tried changing the listener and having another person say it.

My speaking is understood if I get it to talk to me via CLI (set time, for example). I tried different microphone input levels with no change.

/var/log/mycroft/ is a good place to gather information about errors/warnings

Check the audio troubleshooting docs, or start googling those errors in the voice.log and see what you can find to resolve them. Seems like it can’t set up a listening device.

5

Make sure that the user is present in audiospecific groups (permission problems)

6

I tried googling already, but most threads are either very old or don’t have solutions that work.

Audio troubleshooting has some results:

This is strange, because I can get output/input if I give commands via mycroft-cli-client (if I tell him “set timer”, he understands if I say “5 minutes” or so)

changed the quotes to fit in this format (and was too lazy to change it in reverse ‘""’)

there you go:

yeah, he sprincled some `` ` in with my attempt

10

That was the result from permissions.sh.

The result is that now the user is in the groups (there is no output, unless there is a failure)

Not sure if “root” is the best to run with. In this case pulse has to be run systemwide, isn’t it?
@j1nx might have some idea

you have a user mycroft, this has to be run from there.
su mycroft

14

Could it be that the user “mycroft” needs access to pulse?

I’m still not sure why only wake words are not working with this, though.

That’s for sure … see edit above

root@DietPi:~# su mycroft
This account is currently not available.

Is there a necessity that mycroft is sitting on a mount?
BTW i hope you have not exposed owncloud to the outside.

18

Happy to help, but could anyone formulate the exact question to me? Not sure, how/what/when…

19

I guess there are many questions. At least on my side :wink:

First of which, under what user is mycroft running? This setup is a bit confusing. > `
ps aux | grep python

20

I just installed Mycroft via default Dietpi installation.

What’s wrong with my Owncloud setup?
