Reproducing Results for W2V2-FS-20ms

[HildaNya]

Based on the paper, I've successfully reproduced results for Charsiu's FC-10ms, textless FC-10ms, MFA, WebMaus, but I'm having trouble reproducing the pretrained FS-20ms model.
I first downloaded the charsiu/en_w2v2_fs_10ms from HuggingFace into my working directory.
Then I followed the tutorial for generating alignments. When I try

charsiu = charsiu_forced_aligner(aligner='charsiu/en_w2v2_fs_10ms')

, the results are complete gibberish and are nowhere near the paper's results.

When I try

charsiu = charsiu_attention_aligner(aligner='charsiu/en_w2v2_fs_10ms')

, the results are slightly better, but still not as good as that of the paper's.

My questions are:

1. Which one of the above lines should I be using when calling the fs_10ms aligner?
2. Is there perhaps a step I'm missing after downloading the model from HuggingFace?

Thanks so much!
