MMM-AssistantMk2 / MMM-Hotword Issue

@sdetweil I get this error message…

pi@raspberrypi:~/MagicMirror $ sudo apt-get install libatlas-base-dev libatlas3gf-base

sdetweil

@JonoGee have u tried starting MM now?

JonoGee

@sdetweil Just. Still crashing with the same error message

JonoGee

@JonoGee There is discussion about this here…
https://github.com/Kitt-AI/snowboy/issues/126
But i don’t understand what commands I need to run. It doesn’t read very clear to my only being an absolute amateur and all. Does it make sense to you?

sdetweil

@JonoGee is this a pi zero?

pi@raspberrypi:~/MagicMirror $ sudo apt-get install libatlas-base-dev libatlas3gf-base

didn’t install libatlas-base-dev.

may have to install openblas
I had to on my odroid

JonoGee

@sdetweil No. its a Pi3 B+
How do i install openblas then?

sdetweil

@JonoGee Google search. What is r u running raspian, ubuntu?

JonoGee

@sdetweil Hi good morning. I am running Raspian.

JonoGee

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

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.

BJ Duncan

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.

@BJ-Duncan said in MMM-AssistantMk2 / MMM-Hotword Issue:

arecord -l

I get this…

pi@raspberrypi:~ $ arecord -l
**** List of CAPTURE Hardware Devices ****
card 0: sndrpigooglevoi [snd_rpi_googlevoicehat_soundcar], device 0: Google voiceHAT SoundCard HiFi voicehat-codec-0 []
  Subdevices: 1/1
  Subdevice #0: subdevice #0
pi@raspberrypi:~ $

JonoGee

@JonoGee I recognised both devices as 0 so I changed accordingly. Now i get this error message. Mirror opens but closes immediately…

JonoGee

@JonoGee If devices are set as…

hw:0,0

The mirror works, but Assistant/Hotword doesm’t. I just changed to …```
plughw:0

and it crashes

BJ Duncan

What type of microphone is it? Is it USB?
Also, what version of Raspbian are you using? And is it Raspberry Pi 3+ ?

JonoGee

@BJ-Duncan
The Mic is a combined Speaker / Mic HAT as see here… https://www.raspiaudio.com/raspiaudio-aiy

I am running Raspberry Pi3+
Version…

pi@raspberrypi:~ $ lsb_release -a
No LSB modules are available.
Distributor ID:	Raspbian
Description:	Raspbian GNU/Linux 9.9 (stretch)
Release:	9.9
Codename:	stretch

BJ Duncan

Sorry @JonoGee mate, I may not be the best person to resolve as I have USB Mic so my settings will be different to yours.

I will attempt to do some research for you though and see if I can assist with a solution.
