⁠Web Interface

Rhasspy comes with a powerfull web UI (URL: http:<hostname>:12101) allowing to configure the different rhasspy services.

⁠configure a new snowboy wake word

The steps to configure a new snowboy wake word that is generated by snowboy-seasalt service⁠

Assume the new snowboy wake word has the name stemija_macbook_20231026.pmdl

  1. In directory /profiles/en create a sub directory snowboy
  2. copy stemija_macbook_20231026.pmdlto this sub directory
# command to copy a local file into a container
# FYI with command `docker ps` you can find the container id of the rhasspy service.
docker cp stemija_macbook_20231026.pmdl cdebc96fa0fb:/profiles/en/snowboy/
  1. Using the rhasspy web interface change wake word system to snowboy
  2. restart the rhasspy container
  3. Using the rhasspy web interface specify stemija_macbook_20231026.pmdl as Model and set the sensitivy (e.g. set it 0.5)
  4. save the settings.

Your rhasspy profile should look like:

    "wake": {
        "snowboy": {
            "model": "stemija_macbook_20231026.pmdl",
            "sensitivity": "0.5"
        },
        "system": "snowboy"
    }
⁠Setting audio volume

Volume can be set at 2 levels:

  • sink level
  • sink-input level
⁠Setting audio volume at sink level

With following command you can check the sink audio volume:

pactl list sinks

With following command you set the audio volume of sink 8 to 100%

pactl -- set-sink-volume 8 100%

You can use following speaker-test command to test this:

speaker-test -t wav -c 6
⁠Setting audio volume at sink-input level

Use the controller ui for this.

Alternatively you can also do it using following pactl commands:

#  to get the volume of the sink-inputs
pactl list sink-inputs

# to set the volume of a sink-input
pactl set-sink-input-volume #N VOLUME
⁠Audio Recording

Use arecord with Device pulse- so select PulseAudio Sound Server (pulse) in drop down list.
