I cann't install it in the windows.

I don't know if I understand it correctly, but it seems like sclite_mode doesn't really do anything. I tried it with many reference-hypotheses pairs and the results will always be the same whether I set it to boolean True or False.

For reference, here's a small script I tested:

refs = [('a', 'b', 'c'), ('d', 'e', 'f')]
hyps = [('a', 's', 'x', 'c'), ('e', 'f', 'f')]
EPS = '*'
for ref, hyp in zip(refs, hyps):
    print(align(ref, hyp, EPS))
    print(edit_distance(ref, hyp, sclite_mode=False))
    print(edit_distance(ref, hyp, sclite_mode=True))

print(edit_distance(refs, hyps, sclite_mode=False))
print(edit_distance(refs, hyps, sclite_mode=True))
ans = bootstrap_wer_ci(refs, hyps)
print({"wer": ans["wer"], "ci95": ans["ci95"], "ci95min": ans["ci95min"], "ci95max": ans["ci95max"]})

and these are what gets printed:

[('a', 'a'), ('b', 's'), ('*', 'x'), ('c', 'c')]
{'ins': 1, 'del': 0, 'sub': 1, 'total': 2, 'ref_len': 3, 'err_rate': 0.6666666666666666}
{'ins': 1, 'del': 0, 'sub': 1, 'total': 2, 'ref_len': 3, 'err_rate': 0.6666666666666666}

[('d', '*'), ('e', 'e'), ('f', 'f'), ('*', 'f')]
{'ins': 1, 'del': 1, 'sub': 0, 'total': 2, 'ref_len': 3, 'err_rate': 0.6666666666666666}
{'ins': 1, 'del': 1, 'sub': 0, 'total': 2, 'ref_len': 3, 'err_rate': 0.6666666666666666}

For both cases above, the result seems to be giving the same penalty.

{'ins': 0, 'del': 0, 'sub': 2, 'total': 2, 'ref_len': 2, 'err_rate': 1.0}
{'ins': 0, 'del': 0, 'sub': 2, 'total': 2, 'ref_len': 2, 'err_rate': 1.0}
{'wer': 0.6666666666667462, 'ci95': 0.0, 'ci95min': 0.6666666666667462, 'ci95max': 0.6666666666667462}

I think it would be good to support

conda install -c kaldialign kaldialign

All you need to do is the following two steps I will take care of the rest.

Note: Step 1 is optional. If you don't do it, I will do it.

Step 1:

Create an account at https://anaconda.org/

The account name MUST be kaldialign. Otherwise, it is not possible to use -c kaldialign.

After creating the account, visit the following URL:

https://anaconda.org/kaldialign/settings/access

You will find the token at the bottom of that page after clicking Create.

Click view to get its value. (We don't need the name of the API token. Only its value is important).

Step 2

Visit
https://github.com/pzelasko/kaldialign/settings/secrets/actions

Click the button "New repository secret".

Name of the secret should be: KALDIALIGN_CONDA_TOKEN
Value of the secret: Please paste the value of the API token you copied from step 1.

That is all.

Hello, what do you think about using descriptive names for the arguments of edit_distance?
With descriptive I mean something like reference and hypothesis.
In the "plain" edit_distance you only count the numbers of errors, and you can switch the arguments.
It changes, once you report ins/del/sub.

While a change of the code arguments would be a breaking change, it would be nice to have it at least in the README and the docsting. I want to use kaldialign to report ins/del/sub, but now I have to think about, which argument is which.
