reference = "hello world"
hypothesis = "hello duck"

error = wer(reference, hypothesis)

hyps = [item["prediction"] for item in results]
refs = [item["transcription"] for item in results]

error = wer(refs, hyps)

from jiwer import compute_measures

compute_measures(refs, hyps)

[!important] compute_measures(refs, hyps) refs 和 hyps 順序要對
