_voice_activity_detection: division by zero

[Márton Makrai]

Dear People,

I get the error bellow

  File "/home/makrai/tool/python/venv2/local/lib/python2.7/site-packages/bob/bio/spear/preprocessor/Energy_2Gauss.py", line 80, in _voice_activity_detection
    bob.learn.em.train(kmeans_trainer, kmeans, normalized_energy, self.max_iterations, self.convergence_threshold)
  File "/home/makrai/tool/python/venv2/local/lib/python2.7/site-packages/bob/learn/em/train.py", line 61, in train
    convergence_value = abs((average_output_previous - average_output)/average_output_previous)
ZeroDivisionError: float division by zero

Could you please tell me what may have caused this, and suggest a solution?

Thanks
Márton Makrai

Hi Márton,

It seems that the energy across the whole audio sample is the same, as KMeans clusters all energy values in the same point. So, it looks like you are applying voice activity detection to the audio file with a constant tone, i.e., its energy is constant and there is no voice activity. What kind of audio data are you using?

Best,
