DeepSpeech Training own English model for call center speech recognition

That’s really not a lot, but properly re-using checkpoint should not yield empty audio I think. Can you make sure you pass a language model, and use releases values for lm_alpha and lm_beta.

i was using tensorflow 1.14 so upon running got " excenption handler got a new exception".

downgraded tensorflow to 1.13.1 and now new error is coming.
