MMM-Hotword (v2) - whole-new-built

Did you use trainer.sh of the module to make your pmdl? or made it on snowboy website? pmdl is somewhat sensitive so, if you made it on another platform (e.g. your desktop pc) or other device(e.g different mic with your RPI’s), it might not work.
Anyway, How do you figure out `only noise?

I have built two hot words like this to call each page. I call the first page works, but by the time I call the second page is not working? Please point out the error and help me!

Well, you don’t need to use MMM-NotificationTrigger. I can’t understand why you use that. MMM-Hotword itself has the feature of emitting notification(You’re already using.)

{
  fire: "HOTWORD_RESUME",
},
{
  fire: "HOTWORD_PAUSE",
}

It doesn’t make any sense at all. This means “HOTWORD_RESUME” and “HOTWORD_PAUSE” at a same time. Why this part be needed? This would make your MMM-Hotword being paused.

mmm-hotword is working well for me. I created it with first with the website Snowboy, later to make it better with trainer.sh. Sensity 0.5, later 0.9. With my voice it is working well, but for any noice from my wife, youtube movie, mmm-screencash, clocksound etc Google Assistant is activated many times. Also when nothing is said - only some “noise”. The file that is created (when it is Not the hot word) is only a small part of a word/ some sound - but it creates a connection with GA. Any idea how I can make it better?

Frankly says, not many options. There is always possibility of confusing with other sound sources(even noise)
Not surprisingly, real commercial products like google home also misbehavior sometimes. Nobody is saying g of google, but google home be activated.
However, not so may times. Because;

their detector is more dedicated to their own special pattern, which is result of advanced engineering and tech by google, amazon, apple,… ours are not such a level.
they use arrayed mic with phonetic/acoustic science. So they can determine direction, distance and dimension of each sound sources. So they can KNOW what is real voice from human in the room, not noise, not music, not too far, and even not the sound from speaker itself at that moment.

Those are why they can detect precisely.

And by such a reason, Even though I made these modules, I don’t use Hotword. I thought that was fun, but looks a bit ridiculous. In front of mirror, saying “smart mirror” looks somewhat self-contious excessed. :D
Instead, I use generally gesture or finger snap. It looks more cool. ( I think)
