@DongjiGao any interest?

Thanks, Dr. Daniel Povey, JinZr,
Hello @DongjiGao,
1- Is there any script to create lang OTC based on Phone lexicon instead of BPE (k2-fsa/icefall/tree/master/egs/librispeech/WSASR/local/prepare_otc_lang_bpe.py), since the paper showed a better performance in the Phone Based Lexicon over (Bypass Temporal Classification)?
2- Could this Method be used to clean up the errors present in the training transcripts, something similar to original Kaldi (/egs/wsj/s5/steps/cleanup/clean_and_segment_data.sh or clean_and_segment_data_nnet3.sh ) ?
3- Is there any plan to extend that to be used in ONNX (decoder with int8) ?
Thanks in advance,

Thank you for your interest.
- I can check the phone-based script if needed. We modified how we model the star token in OTC (as the average probability of all non-blank tokens instead of an individual token), so I would guess the performance would be similar to using BPE.
- Yes, please refer to this script for more details. It does "flexible alignment" by replacing suspicious tokens or wrongly inserted tokens with a star, and by placing a star where a word is missing.
- We do not have such a plan in the near term. Do you have any suggestions?

Thanks for the quick response, @DongjiGao
1- It would be great if you could check the file in prepare_otc_lang.py (using the phone based lexicon ) and any related files that required to complete the training. I would really appreciate that.
2-It seems quite helpful. I'll definitely give it a try.
3- Perhaps my focusing on utilizing Zipformer could be a primary consideration, and then exporting it to ONNX.
