[JonoGee]

@sdetweil Hi good morning. I am running Raspian.

[JonoGee]

@JonoGee
Error message I am getting now in console is as so…

MMM-GoogleTasks received a module notification: HOTWORD_SLEEPING from sender: MMM-Hotword
module.js:154 MMM-WatchDog received a module notification: HOTWORD_SLEEPING from sender: MMM-Hotword

I have managed to get AssistantMk2 talking to me now in mirror but Hotword/Mic is still not functioning

[sdetweil]

@JonoGee hm… used to be that you needed MMM-Hotword to hear the Alexa or OK Google (or whatever special ‘Hot’ word), that signaled MMM_AssistantMk2 to listen for search words or commands…

each used the mic separately, Hotword first, then Assistant.

I know Sean has released new versions, which I haven’t tested yet

[JonoGee]

@sdetweil As far as I am aware, I have used the latest released versions of each. I guess I’ll just have to wait and see if someone updates it or fixes problem or something. Thanks anyway for your time and help. I have made a bit of progress though. It just seems to be Snowboy now.

Have you test your microphone to see if it working in general?

From home directory:

arecord test.wav

and talk for about 5 seconds into your microphone.
Then cancel that by Ctrl+C

Once you have cancelled the test check your directory to ensure that the ‘test.wav’ file is there:

dir

if your file shows up then you can test that file to ensure it recorded your voice from the microphone:

aplay test.wav

You should be able to hear back what you just recorded.
If you can, that means it is a configuration setting that just needs to be tweaked. If not, then there is something wrong with either the microphone settings or audio settings within the pi itself.

I will keep monitoring and let me know how you go.

[JonoGee]

Just tested. Recording & playing back fine with arecord and aplay. No problems and no error messages. Thanks for taking the time for getting in touch anyway. I’d almost given up on this.

No dramas at all.

Now you need to double check that you are pointing to the correct device number for your audio with the Assistant module.
In a terminal at the root directory (pi@raspberrypi:~ ) Check the device list for audio input:

arecord -l

This should provide you a list of CAPTURE Hardware Devices. The numbers you want to write down is the Card number, and device number.
As an example on my device I have it as Card: 2 Device: 0

Now within the config.js of the MagicMirror ensure that the device number is the same. Here is what it looks like within my config.js:

{
		  module: "MMM-AssistantMk2",
		  position: "bottom_bar",
		  config: {
		    record: {
		      recordProgram : "arecord",  
		      device        : "plughw:2",
		    },
		
		    notifications: {
		      ASSISTANT_ACTIVATED: "HOTWORD_PAUSE",
		      ASSISTANT_DEACTIVATED: "HOTWORD_RESUME",
		    },
		  }
		},
		{
		  module: "MMM-Hotword",
		  config: {
		    chimeOnFinish:null,
		    mic: {
		      recordProgram : "arecord",  
		      device        : "plughw:2",
		    },
		    models: [
		      {
		        hotwords    : "smart_mirror",
		        file        : "smart_mirror.umdl",
		        sensitivity : "0.5",
		      },
		    ],
		    defaultCommand: {
		      notificationExec: {
		        notification: "ASSISTANT_ACTIVATE",
		        payload: (detected, afterRecord) => {
		          return {profile:"default"}
		        }
		      },
		      afterRecordLimit:0,
		      restart:false,
		    },
		  },
},

Notice within both my modules because my card number is ‘2’, that the

device : "plughw:2",

So make sure your number corresponds with your Card number.

Give that a test and we will go from there.

arecord -l

I get this…

pi@raspberrypi:~ $ arecord -l
