{
  module: 'MMM-Snowboy',
  config: {
    Frontend: false,
    Model: "smart_mirror"
  }
},

this is the default configuration defined if you don't define any value

{
  module: 'MMM-Snowboy',
  config: {
    debug: false,
    AudioGain: 2.0,
    Frontend: true,
    Model: "jarvis",
    Sensitivity: null,
    micConfig: {
      recorder: "arecord",
      device: "plughw:1"
    },
    onDetected: {
      notification: "SHOW_ALERT",
      parameters: {
        type: "notification",
        message: "Detected !",
        title: "MMM-Snowboy",
        timer: 10 * 1000
       }
    }
  }
},

• debug - turn on/off debug mode.

• AudioGain - set the gain of mic. Usually you don't need to set or adjust this value.

• Frontend - set pre-processing of hotword detection. When you use only snowboy and smart_mirror, false is better. But with other models, true is better to recognize.

• Model - set the name of your detector. Available: "smart_mirror", "jarvis", "computer", "snowboy", "subex", "neo_ya", "hey_extreme", "view_glass"

• Sensitivity - Override default sensitivity value for applied model defined in Model.

  • Value could be within a range from 0.0 to 1.0.

  • Default sensitivity values for preconfigured models are:

    • smart_mirror: 0.5
    • jarvis: 0.7
    • computer: 0.6
    • snowboy: 0.5
    • subex: 0.6
    • neo_ya: 0.7
    • hey_extreme: 0.6
    • view_glass: 0.7
    • alexa: 0.6

  • null will set default sensitivity.

• recorder - record program, rec, arecord, sox, parec is available.

  • On RaspberryPi or some linux machines, arecord is better.
  • On OSX, rec is better.
  • If you prefer to use pulse audio, parec would be available also.

• device - recording device (microphone) name of your environment. (e.g. "plughw:1")

  • Find proper device name by yourself. (arecord -l will be help on Raspberry Pi)

• notification - notification name to emit when the hotword is detected.

• parameters - payload to send with your notification.

MMM-Snowboy can receive notification for start or stop listening

• SNOWBOY_START: Start listening with your prefered hotkey
• SNOWBOY_STOP: Stop Litening

• this module don't need position, because it don't use any visual
• With npm install, you can generate a proper micConfig {} configuration.

This module use my personal @bugsounet/snowboy library build for node and will be maintened
Original snowboy@kitt-AI source will be unmaintened soon
