[Question] Difference between `blank` and `space` character in ASR quartznet?
`space` character is a regular delimiter between words [` `]. Usually, it is also returned for silent segments. 
`blank` symbol is a special extra character in CTC modeling that allows representing double characters, for example. It is removed from final decoded transcript. More details could be found in the following great paper: https://distill.pub/2017/ctc/ . That's very helpful, thanks 
How to differentiate the meaning of these two characters? Which one represents silence, gap for next word or the end of word? Thanks in advance :)
