Tests: Linux/Mac: 
With this adapter you can control ioBroker with voice in many different languages.
It uses open source package snowboy to detect the hotword and google speech service to convert the recorded voice to text. Only 5 seconds after the hot word will be recorded.
To compile the snowboy (before the installation of this adapter) you need some linux packages, wich can be installed as follow:
sudo apt-get install libmagic-dev
sudo apt-get install libatlas-base-dev
sudo apt-get install build-essential
sudo apt-get install sox libsox-fmt-all
For good recognition quality you need a good microphone. I tested it with UMA-8 USB mic array.
List all record devices:
arecord -l
If you have extra micro, you must set the default microphone:
**** List of CAPTURE Hardware Devices ****
card 1: SpkUAC20 [miniDSP VocalFusion Spk (UAC2.0], device 0: USB Audio [USB Audio]
Subdevices: 1/1
Subdevice #0: subdevice #0
Edit /usr/share/alsa/alsa.conf and replace defaults.pcm.card 0 with defaults.pcm.card 1, because in example there is a microphone on card 1.
You can test the microphone with rec test.wav.
For text recognition after the hot word was detected this adapter uses google speech API. To enable it you must get your own credentials and paste it into configuration as JSON.
The instruction can be found here: https://www.npmjs.com/package/@google-cloud/speech#using-the-client-library or here
Google JSON file looks like:
{
"type": "service_account",
"project_id": "ыаыаыаыва",
"private_key_id": "ун457567565",
"private_key": "-----BEGIN PRIVATE KEY-----\шукгншугкнеушеуке\n-----END PRIVATE KEY-----\n",
"client_email": "рапрарапрапр.iam.gserviceaccount.com",
"client_id": "апрапрарапрапр",
"auth_uri": "https://accounts.google.com/o/oauth2/auth",
"token_uri": "https://oauth2.googleapis.com/token",
"auth_provider_x509_cert_url": "https://www.googleapis.com/oauth2/v1/certs",
"client_x509_cert_url": "https://www.googleapis.com/robot/v1/metadata/x509/аапрарарапрапра.iam.gserviceaccount.com"
}
And just the whole copied text insert into iobroker configuration.
Default hotword is snowboy or sonus, but you can create your own "hot word" model here https://snowboy.kitt.ai/hotword/ and upload it to adapter.
You have generally 2 possibilities to parse the text and trigger a command:
- text2command
- javascript
You can set trigger words in text2command, for that you must select the text2command instance in the configuration.
Write a script that will parse the text appeared in sonus.X.data.detected, where X is instance of sonus adapter.
Script should be like this one:
on({id: 'sonus.0.data.detected', change: 'any'), obj => {
console.log('Detected words: ' + obj.state.val);
let command = '';
if (obj.state.val.match(/on|ein/)) {
command = true;
} else if (obj.state.val.match(/off|aus/)) {
command = false;
}
if (command === '') {
console.log('Cannot detect command');
} else {
if (obj.state.val.match(/light|backlight/) && obj.state.val.match(/living/)) {
setState('hm-rpc.0.Q92837293.1.STATE'/* Living room light */, command);
} else {
console.log('Cannot detect room or function');
}
}
});
