bug openwakeword

[thatsri9ht]

Hello,

When I activate the pretrained models in OpenWakeWord, for example, the word 'Hey_jarvis' is triggered when I only say 'Hey_ja'. Is there a solution to this issue?

Didn't tried by myself, just saw this as option: #110 (comment)

I wouldn't consider this behavior a bug, rather it is one of the core challenges when training wakeword models. It is (nearly) impossible to avoid activation on words that sound extremely similar, or have a subset of the phoneme sequence in the target wakeword. There are methods to reduce this behavior, and the comment that @eugene-orlov-sm linked is a good summary of approaches that seem to work reasonably well.

Thank you for providing the file "openwakeword_features_ACAV100M_2000_hrs_16bit.npy" generated automatically from 2-second audio clips. However, my wake-up word is 3 seconds long. Can I still use this file to train the model FOR negative sample?
