Using the node-red-contrib-personal-wake-word node

Hello All,

I'm using this node along with the @kevingodell/node-red-ffmpeg node to create a compatible audio stream from my mic to feed into it. The issue is that I'm not sure I'm configuring the wake word setup correctly. I wanted to ask if there is anyone here who has had experience using this node? (especially preparing the wake-word audio files). I tried to record a couple of clear samples of my saying "Hey Computer" but it doesn't seem to recognize them.

The node is based on the node-personal-wakeword library. Does anyone know if there are any tools to help make the wakeword audio samples?

Here's the portion of my flow that I made for testing this node:

Any feedback and/or pointers greatly appreciated!

If you click on the node and open the 'Help' in the side bar and then click the 'wakeword-config` you will get information about creating the wake word:

Note: the node hasn't been updated three years and the author has not been seen on GItHub since 2021 so I would assume it has been abandoned.

Thanks, I currently have a path to the directory containing my .wav audio samples setup in the configuration node:

Knowing that this node has likely been abandoned. Would you happen to know if any alternatives that people are using nowadays? (Or if not a node, a library that I could implement in a function node or something). I'm just look for the simplest way to go about doing this.

Sorry but no I don't. HOWEVER a search of the forum found these threads that might be useful:
