Snowboy-CustomMaker

KiboOst · January 31, 2020, 11:39am

iya!

Like some of you ever know, I had problems with getting custom wakeword with snowboy working fine. I mean, good detection, and no false positive!

I finally get it running fine, even better than snips one actually ( ) after doing home-work and writing a few tools to achieve this.

I get some time to clean all this and share all tips and tools I used for that, so here it is :

Let me know if the doc is understandle, if downloading and running scripts goes fine, etc.

Also, english isn’t my mother language, so if some part need some rewrite, don’t be shy I won’t feel ashamed (well, maybe, but I will do correction )

Good work! I will try it and see how far I get.
I just need to get up with a good wake word

Good job Kiboost, I will try it also.
Currently I used my own snowboy wakeword (nestor) its not so bad but sometimes with a lot of false postive.

Thanks for your work !

Hi @KiboOst,

I created a buster image sdcard and follow your Howto.
But I got this message when I tried python3 snowboyRecord.py --wakeword nestor

“OSError: libasound.so: cannot open shared object file: No such file or directory”

KiboOst · February 1, 2020, 10:17am

Hi,

I see why it does that, seems you don’t have libasound which was installed by seed driver on my pi

Can you redownload snowboyRecord.py and give it a try ?

raqpub · February 1, 2020, 10:58am

Well done.
The 3 .wav are well created but I have these lines below (I don’t know if its important or not)
Fyi I use a Jabra and I have created the $HOME/.asoundrc to use it.

At next step (python3 snowboyTrain.py --token … ) I have this error :

If your wav file are good when you play them, all is good then. Never saw this the correction I did was because it can’t load your Alda lib to prevent alsa warnings to show but these are not warning but error. Seems your alsa config are problematic.

But if you have three good wav files, cut the leading and trailing noise in audacity and get your pmdl to test.

KiboOst · February 1, 2020, 11:20am

Seems your wav files are corrupted then
Did you tried to play them ? Can you listen your voice ? Did you re export them from audacity ?

raqpub · February 1, 2020, 11:32am

Yes OK with aplay and its me
I make two wakeword nestor and pepper. pepper reexported from audacity not nestor.
The 2 wakewords generate this error.

I think I’ll reinstall all in my original rhasspy sdcard to see is there is a difference…

EDIT : same issue with sdcard rhasspy.

KiboOst · February 1, 2020, 12:25pm

Could you send me one of these wav file in mp ?

raqpub · February 1, 2020, 12:44pm

upload of wav impossible with “messages” when I clic on your name (just pictures authorized)

KiboOst · February 1, 2020, 12:45pm

Rename it to .jpg ? Or .zip ?

raqpub · February 1, 2020, 12:47pm

I tried, but the upload try to determine the size and he can’t.
EDIT : ==> Je passe par community Jeedom + renommé en .txt

EDIT 2 : Take the time ! I’m not in the hurry

KiboOst · February 1, 2020, 1:07pm

Ok, had same error, can you redownload snowboyTrain.py and retry ?

raqpub · February 1, 2020, 1:17pm

KiboOst · February 1, 2020, 1:18pm

3 isn’t valid for --age, try 30
or python3 snowboyTrain.py -h

raqpub · February 1, 2020, 1:20pm

Great !

KiboOst · February 1, 2020, 1:20pm

Ahah, now test your wakeword

I’m looking for a way to automatically cut leading and trailing noise to avoid having to do it manually in audacity. If there is some pyaudio guru there

raqpub · February 1, 2020, 1:28pm

Yes. thks.

Audacity is not so difficult
