What is Word error rate?
Also called: WER
Word error rate is the percentage of words a speech recognition system gets wrong, measured against a correct transcript.
Published figures are almost always measured on clean, read speech in a well-resourced language. Real calls are noisy, accented, and code-switched.
Why it matters for Indian calling. A vendor's WER for English tells you nothing about its performance on a Rayalaseema speaker. Ask for the figure on the language and line quality you will actually run.
