After a wake word ist recognized (Debug node output is good) it throws an error which leads to a Node Red restart:
20 Oct 15:02:06 - TypeError: Cannot read property 'destroy' of null at Timeout.node.recoverTimeout.setTimeout [as _onTimeout] (/home/pi/.node-red/node_modules/node-red-contrib-personal-wake-word/wakeword.js:173:31) at ontimeout (timers.js:436:11) at tryOnTimeout (timers.js:300:5) at listOnTimeout (timers.js:263:5) at Timer.processTimers (timers.js:223:10) nodered.service: Main process exited, code=exited, status=1/FAILURE nodered.service: Failed with result 'exit-code'. nodered.service: Service RestartSec=20s expired, scheduling restart. nodered.service: Scheduled restart job, restart counter is at 1.

I have read most things I have found about voice recognition and found your Nodes. I have a specific thing I want to do but would like to be pointed in the right direction. I tried to send you a mail but could not find any details. If you have time I would be most grateful if you send me a ping at [email protected]. In short I want to use Node Red to listen to 15 samples of words and trigger VLC to play files depending on the input. I am trying to use a rpi screen connected to a real pinball machine. If the pinball is playing "next match Germany" I would like to play the game from 1994. With Germany. Or if it is the final play the final etc. (It is a World Cup Soccer 1994 Pinball)

Hello,
I try to implement a wake-word (on my RPi 4 with Raspbian) in Node-Red.
It looks good, I follow your instructions and the button "wakeword" is in the status "listen" - and thats all.
My sox-record give a "stream of raw buffers". How I can see if there is something to do for the "wakeword"? The status "Listen" noch changed.
I test the "sox-record" and change the output to a wav. That's OK, I got a correct wav-file.
In the sox-record-configuration there is a "processing buffer" where I don't find any info whats the correct value. I try 4096.
With best regards,
René

After updating from NodeJs 14.x to 16.x I ll get this message and node red does not work anymore.
