VoiceControl module

Medo

Searching for endless hours now, but no solution in sight…

Im trying to trigger the mm-music-player module with this voicecontrol module (i say “MUSIK ON” and the mm-music-player starts a certain mp3 file). But no luck…

My microfone can record audio (tested with arecord …) …

(note: i had to change my “sudo nano /usr/share/alsa/alsa.conf” and the entries “defaults.ctl.card 1” and “defaults.pcm.card 1” from “0” to “1” to get my USB microphone working/recording)

…and my mp3 soundfile can be played (tested with “omxplayer -o hdmi …”) - and also if i click on the mm-music-player-module…

pm2 logs mm (after a reboot) shows this:

I…

installed the voicecontrol and mm-music-player
double checked the code
changed the mp3 file with another
implemented the code like “GinSeng” stated some lines above.
created the hotwords over at snowboy and copied them to “/MagicMirror”, “voicecontrol” and “mm-music-player” directories
…
But im not able to find the problem…

Any suggestions?

Thanks a lot for your help…

Hello guys, it seems I have the same problem as @frodrd00 and @Medo and cannot properly run the voicecontrol module. In my case I want to use the camera module which works together with the mentioned one. I’ve checked the voicemodule.js to match with its corresponding declaration in config.js and everything looks fine.

**config.js**
{
    	module: 'voicecontrol',
    	position: 'bottom_left',
    	config: {
        	models: [
            	{
                	keyword: "Show Camera",
                	description: "Say 'Show Camera' to display camera",
                	file: "ShowCamera.pmdl",
                	message: "SHOW_CAMERA"
            	},
            	{
                	keyword: "Hide Camera",
                	description: "Say 'Hide Camera' to hide camera",
                	file: "HideCamera.pmdl",
                	message: "HIDE_CAMERA"
            	},
            	{
                	keyword: "Selfie",
                	description: "Say 'Selfie' when camera is visible",
                	file: "Selfie.pmdl",
                	message: "SELFIE"
            },
        	]
    	}
},

voicecontrol.js

models: [
	{
		keyword: "Show Camera",
		description: "Say 'Show Camera' to display camera",
		file: "ShowCamera.pmdl",
		message: "SHOW_CAMERA"
	},
	{
		keyword: "Hide Camera",
		description: "Say 'Hide Camera' to hide camera",
		file: "HideCamera.pmdl",
		message: "HIDE_CAMERA"
	},
	{
		keyword: "Selfie",
		description: "Say 'Selfie' when camera is visible",
		file: "Selfie.pmdl",
		message: "SELFIE"
	},
]

How did you manage this problem?

@thereisnotry87 hi, no need to mention voicecontrol commands in config.js file, just mention only as below , make sure you have installed

sudo apt-get install python-pyaudio python3-pyaudio sox

and
copy all pmdl files in MM root folder

{
module: 'voicecontrol',
	    position: 'top_left',
	config: {
            }
},

go to /usr/share/alsa/alsa.conf and change 0 to 1 in below parameters

defaults.ctl.card 1
defaults.pcm.card 1,

this worked for me.

hi,
i am having difficulty in adding voicecontrol module on my magic mirror.
i want to use voicecontrol to use camera.
so can someone help me with the steps to follow?

pepemujica

Hi! is it possible with this module to hide/show different modules or even switch profile with profile switcher?

Kind regards

Hello Guys , @alexyak .
I;m running this module and hot word detection is working ok, i used my own keyword and send notfication to other modules. I can see in console.log .

MMM-temp-ds18b20 received a module notification: LUSTRO from sender: voicecontrol

In all my modules. but i’m unable to run for example script … I tried to modify node_helper.js

/* Magic Mirror
 * Module: voicecontrol
 *
 * By Alex Yaknin
 * MIT Licensed.
 */

const NodeHelper = require('node_helper');
const exec = require('child_process').exec;

module.exports = NodeHelper.create({
    start: function () {
        this.started = false;

    },

    socketNotificationReceived: function(notification, payload) {
                if (notification === "CONNECT") {
                        this.startRecognition(payload);
                        return;
                }
                if (notification === "LUSTRO"’) {
                        exec("/opt/vc/bin/tvservice -o", null);
                //      this.autosleep();
              }
        },

but it is not working … ;)

Hello everybody, I try to use this voicecontrol module AND mmm-alexa in the same time (mmm-alexa need to be trigger by a notification. That where voicecontrol is interesting at the moment) but because both the module use the mic, it doesn’t work.
If I put only one module at the time no problem. Both of them in the same time, voice control doesn’t work.
How can I use the same mic for two different module ?

disakos

@romain , do you use voicecontrol module to run some scripts ? If so please let me know how to do it … ;) my module is detecting my voice … but i’m unable to run something … ;)

romain

@disakos I didn’t use it to run script, I wanted it specificaly for mmm-alexa. However I did check that the other module received the notification It send.
I did that by writing my own useless module that only print the notification it received.
You need in your main file a

notificationReceived: function(notification, payload, sender){
   //Whatever you want to do
},

This is different to “socketNotificationReceived” , socket notification receive only deal with your node helper file. But “notificationReceived” catch notification send from a module to another.

With that in mind, you can add the notificationReceived thing to the module you want to control with the voicecontrol module or add whatever you need to it if it already exist

romain

I did it, It wasn’t easy but it’s work, I can use voicecontrol and others voicecontrol driven module at the same time.
I had to change my /etc/asound.conf file again (yes, again. Because changing it already solve some of my issue on the past)

before my file looked like this:

pcm.!default {
        type asym
        playback.pcm {
                type plug
                slave.pcm "hw:0,0"
        }
        capture.pcm {
                type plug
                slave.pcm "hw:1,0"
        }
}

Easy enough when you know what your doing (that wasn’t my case). this file is there to say what is the default device to playback and capture (A lot of application or software just use the default device so if the default configuration isn’t working for you, you need to change it for you.) In my cas ethe microphone is the “hw:1,0” and my speaker is the “hw:0,0”

That worked well when my microphone is used by one application at the time. However, not so much when it need to be used by multiple ones.
So my new /etc/asound.conf file is looking like this now

pcm.myTest {
    type dsnoop
    ipc_key 2241234
    slave {
        pcm "hw:1,0"
        channels 1
    }
}

pcm.!default {
        type asym
        playback.pcm {
                type plug
                slave.pcm "hw:0,0"
        }
        capture.pcm {
                type plug
                slave.pcm "myTest"
        }
}

instead of directly say that my input device is the “hw:1,0” I say it’s “myTest”, which is describe above. myTest’s type is “dsnoop” , that’s whats allow the michrophone to be use by multiple application at the same time. The ipc_key is there with a random value because when I tested with arecord, it asked me to put one. The channels is there because it was on the documentation ( http://alsa.opensrc.org/Dsnoop ) >.> not sure what it does though.
And there you go, after that I could use two voice control things at the time
