Description

Currently arabic numerals and symbols in whisper transcript cannot be aligned, needs to be phonetic alphabet.

Need to perform inverse of normalization in https://github.com/m-bain/whisperX/blob/main/whisperx/normalizers/english.py

Such that numbers and currencies are converted to their phonetic word form.

E.g. "$300" -> "three hundred dollars"

To perform wav2vec alignment.

Then convert back to symbol form, and assign timestamps.

Contributor guide

Research direction
Study the existing normalization in https://github.com/m bain/whisperX/blob/main/whisperx/normalizers/english.py, implement a function to convert numbers and currencies to their phonetic word form (e.g., $300 > three hundred dollars), then integrate with wav2vec alignment and convert back to symbols with timestamps.
