Hi.
Sorry if this is a basic question, but I am a beginner with pynini and confused with the logic behind the TimeFst in En inverse text normalization.
In the file nemo_text_processing/inverse_text_normalization/en/taggers/time.py,
the time components are tagged into minutes and hours as required
e.g. twelve thirty -> time { hours: "12" minutes: "30" }
e.g. twelve past one -> time { minutes: "12" hours: "1" }
In the file nemo_text_processing/inverse_text_normalization/en/verbalizers/time.py,
the same tagged string are verbalized and we remain only with the time
eg. time { hours: "12" minutes: "30" } -> 12:30
I am unable to understand how the second case from tagged sentence -> 'time { minutes: "12" hours: "1" }' is handled in the code.
Is it by reversing the terms while processing or is it done during the final processing in FinalVerbFst?
