Snowboy error/ implementing with Matrix Voice and google assistant

#1

Hey it’s me again!

I have a few questions.

  1. When using the Snowboy demo.py i come up with this error:

i found this topic: [Solved] Kitt_ai wakeword engine still not working on Matrix VOICE

But I’m not sure I comprehend the solution.

could someone explain this to me and how I could fix it?

I’m trying to use snowboy to replace the “Ok, Google” hotword from:

the assistant works fine but snowboy is giving me issues

  1. could someone explain to me HOW to implement snowboy to into google assistant itself? as I’m simply confused with this

3.(OPTIONAL) lastly is there a way to send a sperate .wav file to send a command? as my end goal is to say the hotword and talk directly to a dialogflow bot. so instead of saying “Ok Google” and “talk to test bot” separately I want to say “hey test bot” and it would automatically send both commands.

my thought process is to send a pre-recorded .wav file with the “talk to test bot”

if anyone could help me with these issues or can link me to somewhere that would be helpful I’d be greatly appreciated

thanks,
Mashiro

Update: i got Snowboy to function by using the arecord variant of the decoder here:

Update 2: I got snowboy to RUN the command to start the assistant but how do i get it to replace OK google?

Snowboy listening but not responding (pyaudio)
