Hey Spyder, any chances made to that file will be overwritten from your home.mycroft.ai settings.
There’s instructions to set this up at:
https://mycroft-ai.gitbook.io/docs/using-mycroft-ai/customizations/wake-word
It starts with Precise wake words, then goes onto PocketSphinx. If you want a custom Precise model but not comfortable with the training aspect you can ask in this thread and a community member might help you out, you’d just need to provide the relevant audio samples: Custom wakewords R Us!
I recommend using the mycroft-config helper command to edit your config (in mycroft-core/bin if you didn’t add these to your $PATH during setup). This tool validates your configuration when you save the file. It’s so easy to miss a comma or something and this saves a lot of frustrating debugging.
