Sources
Guides are based on primary sources wherever possible: official product documentation, standards such as WCAG, regulations and agency guidance, and published research. Where a fact may change, such as a deadline or a menu location, we say so and date the page.
Accuracy estimates
Per-language accuracy estimates are based on the per-language results OpenAI published for Whisper. They are estimates, not guarantees.
Comparisons
Comparison pages describe how cloud transcription services generally work and do not quote competitors’ prices, which change. We name trademarks only to identify products.
Updates and corrections
Every page shows when it was last updated. If you find an error, tell us and we will correct it.
Independence
We are not paid by the companies we mention. Advertising is labelled and does not influence content.
