Custom wakewords with pi hat 2mic setup

[sly viper]

Hello - I am looking for some assistance on adding custom a custom wake word to the “onboard” wakewords on my pi-sat 2mic device. I have trained and added it to my HA server but when I update the config on the PI the device fails to initialize. I am assuming that I am missing a configuration step. Any guidance would be greatly appreciated!

Wyoming satellite is most probably using local Openwakeword (installed on the Pi itself). So you need to put new wake word model to Pi, and change config there.

Thank you and was thinking that, any idea on how to accomplish that? I’m a bit of a newbie

Checkout the README for Wyoming: https://github.com/rhasspy/wyoming-satellite
Specifically the section "Local Wake Word Detection". There's setup with required directory and changes to service command to make it work.

Thank you!!! This is what I’ve been looking for just not sure how to define the path, I have my LLM, whisper and piper offloaded on a better computer that is not running HA. So should I point to the location where I’ve added the files on the HA share file or is there a better location? Sry for all the questions, I’m still learning and any examples would be greatly appreciated!

No, you have Pi: put the model file there, say, in the folder wyoming-openwakeword/models/your_wakeword.tflite , and then:

cd wyoming-openwakeword/
script/run \
  --uri 'tcp://0.0.0.0:10400' \
  --custom-model-dir './models'
  --preload-model 'your_wakeword'

Thanks again!! I can see the dir. but unsure how to copy the file. I’m running win11 and using ssh in terminal to connect to the pi.

You will need program like WinSCP. It can copy via SSH.

Thank you for all your help, I’m reading about samba now but will look into winSCP.

Yeah if you just want to copy one file, it's easier to go WinSCP. Samba is more suitable for permanent access.
