Porcupine wake word

[thegnuu]

I am currently trying to add a wake word to porcupine but somehow I am not able to figure out how this is done.

I just added it to my profile at the following path /share/rhasspy/profiles/en/porcupine/jarvis.ppn.
This matches the config of my Rhasspy Add-On.
Setting the name of the file is not working and the refresh button does nothing as well.

Am I missing something here?

I used Rhasspy on a dedicated PI before and setting this up worked without any issues.

Hi @thegnuu. I am having the same issue.

I was a little surprised that there was no ../en/porcupine/ directory with .ppn created automatically on choosing porcupine as the wake word engine with Rhasspy (on Hassio). I created the directory manually and placed a downloaded .ppn file in there. Save and restart and "refresh" causes timeout after a quite a few seconds and no words populate the Available Keywords: box.

Have you managed to resolve the issue by any chance?

I notice that there are errors in the Rhasspy log:

[ERROR:2021-01-21 16:17:03,233] rhasspyserver_hermes:

I hope someone has cracked this one!

@MikeLDPT It seems like an issue with Rhasspy itself.

I have not tested it right now, since I just used one of my spare PIs to run Rhasspy on it, but it looks like there was an update of porcupine in 2.5.9 which might resolve this issue!

See this:
https://community.rhasspy.org/t/wake-word-porcupine-help-is-needed/2104/14?u=thegnuu

Have you tested it with 2.5.9?

Same issue with 2.5.9

[MikeLDPT]

Yes, I can concur that I'm running 2.5.9.... The changelog in Rhasspy mentions: "Upgrade porcupine wake word system to 1.9". Seems the latest version of prcupine is 1.9.

I have tried using Raven insetad and that does not seem to have any issues with updating the wake config files. It places the .wav files in the \rhasspy\profiles\en\raven directory OK.

It "feels" like an error with Porcupine knowing exactly where the .ppn file is. No idea really though as yet.

I was a little surprised that there was no ../en/porcupine/ directory with .ppn created automatically on choosing porcupine as the wake word engine with Rhasspy (on Hassio).

The porcupine Python package includes all the default keywords in its install directory. Only custom keywords need to go in the profile.

I just added it to my profile at the following path /share/rhasspy/profiles/en/porcupine/jarvis.ppn.

This looks correct to me, but I will need to test again on Hass.io. Testing on my desktop, creating a ".ppn" file in the en/porcupine directory and hitting Refresh immediately shows the new keyword.

While I look into this more, I'll update the web UI to show the exact path where it's expecting the files 👍

[MikeLDPT]

Thank you Synesthesiam. In case it helps, here are a couple of screen shots. I am running this under Hassio on a raspberry pi and assume I have chosen the corect format .ppn file. I downloaded again the porcupine_raspberry-pi.ppn from github and placed it here:

I then chose Porcupine as the wake word engine. Raven was previously chosen. The configuration looks like this, and when you click on the drop down to select "available keywords" nothing is there. Clicking on refresh causes the timeout error after a number of seconds:

which causes the error messages in the log:

Raven on the other hand had no problems putting the Wav files in its alloted directory, and so it seems raven can find and access the directory area :
