conformer transducer timestamp extraction
Good day! Thanks for your hard work!
I am trying to extract timestamps for a model stt_en_conformer_transducer_large
Following https://colab.research.google.com/github/NVIDIA/NeMo/blob/stable/tutorials/asr/ASR_with_Transducers.ipynb#scrollTo=xkv_x8NAfpX3
But I'm having difficulty converting timestamps:
"Note that each timestep here is (roughly) timestep∗total_stride_of_model∗preprocessor.window_stride seconds timestamp" - I can extract "timestep" from hypotheses, but model.preprocessor doesn't have a window_stride field and I'm not sure which value to use here. Also, I couldn't figure out where the "total_stride_of_model" value comes from. Do I understand correctly, total_stride_of_model == len(audio) / 'window_stride'? By the way, the 'window_stride' field is also missing from model.preprocessor.
Thank you!
