What is "text_no_preprocessing" used for in manifest.json exactly?
Hello. I tried using extract_sup_data.py script, where my manifest.json file had only these 4 keys: "audio_filepath", "text", "text_no_preprocessing" and "duration". The script didn't work, but when I removed "text_no_preprocessing" key it worked. I guess it would have initially worked if I had additional "text_normalized" key. So my questions are:

- What is the purpose of "text_no_preprocessing" key? 
- How the model recognizes punctuation in input sentence when manifest.json only has "text" keys?

Thank you!
