Research context, with original-source dates: Alec Radford and colleagues reported 680,000 hours of supervision in the original Whisper paper (2022-12-06); this is a research training quantity, not a WhisperAITranscribe accuracy claim. [Original paper](https://arxiv.org/abs/2212.04356).

> "approximately 1000 hours of 16kHz read English speech" — Vassil Panayotov and Daniel Povey, [LibriSpeech / OpenSLR](https://www.openslr.org/12/), associated with the 2015 corpus paper.

> "Captions are provided for all prerecorded audio content" — W3C, [WCAG 2.2, criterion 1.2.2](https://www.w3.org/TR/2023/REC-WCAG22-20231005/#captions-prerecorded), 2023-10-05. This excerpt concerns synchronized media; the criterion includes an exception for clearly labeled media alternatives for text.

An illustrative WER calculation is 5 errors / 100 reference words = 5%; it is not a measured product result. See the quality guides for normalization and error accounting.
