API

Each takes a single utterance (str) or a corpus (Sequence[str]), plus an optional WerConfig to override the default CANONICAL profile.

Function	What it scores
wer(ref, hyp)	Corpus Word Error Rate (the default metric)
cer(ref, hyp)	Character Error Rate
numeric_wer(ref, hyp)	WER over numbers only - safety-critical digits
agreement(a, b)	Symmetric [0, 1] overlap of two transcripts (1 = identical), for model-vs-model voting
ladder(ref, hyp)	WER at each normalization rung, raw to semantic
process(ref, hyp)	Full WerResult - every metric plus per-utterance and distribution stats

normalize(text) exposes the normalization step on its own. WerConfig, the profiles presets, and the vocab term lists let you tune phraseology handling.
