Implement a `NoTransform` operation

[nikvaessen]

what would you think about adding a "NoTransform" placeholder class ?

This would be used, if user wishes to do all the transforms himself, example here:
KarelVesely84@1c5f29d#diff-aae25c8b196777e4abeb01845ca517591f65580977ee7d1f639b5bbf16e26d9d
(plus a registration is necessary in transforms.py header to __all__ variable)

Or can there be something similar already in the code ?

Thank you & best regards
Karel

This behavior can currently be done with:

import jiwer

ref = [['already', 'transformed']]
hyp = "needs to be transformed"

jiwer.process_words(ref, hyp, reference_transform=jiwer.Compose([]))

Can you specify why the default transformation is problematic in your case? It is quite minimal.

wer_default = tr.Compose(
    [
        tr.RemoveMultipleSpaces(),
        tr.Strip(),
        tr.ReduceToListOfListOfWords(),
    ]
)

Aha, I see, you are right.
(Maybe I am just a little "obsessed" by doing things on my own)

Thank you for the suggestion.
