Unable to use my speaker recognition model (model-spk)

Hi, this library is awesome, especially because it can be used offline. I'm a newbie in speaker recognition. I build my speaker recognition model using VoxCeleb v2 recipe in Kaldi and unable to use it on test_speaker.py to replace model-spk. I used default model for the speech recognition model (vosk-model-small-en-us-0.15).

Kaldi 5.5
Vosk 0.3.45

One of my model:
