The absolute value of WER is highly dependent on test-set difficulty: on read-speech, low-noise corpora, the same model's WER may be only 5%; switched to real recordings with accents and background noise, the same model's WER may double or even higher.

UnverifiedLooking at the WER published by vendors alone is of limited value; it must be judged in combination with the noise conditions and languages of the test set.76% similarUnverifiedOn the 50 samples of LibriSpeech test-clean, the WER gap between Parakeet and Whisper is 0.39 percentage points, which is on the same order of magnitude as the noise introduced by text normalization and cannot clearly distinguish which model is better.70% similarUnverifiedAccording to the uploader's actual testing, when the reference audio is shorter than 6 seconds, the gap between the cloned voice and the original voice becomes noticeably larger.68% similar
