The label identifies the text source
Apple’s current subtitle guide says supported apps can label subtitles Transcribed when produced from spoken audio and Translated when translated into another language. Those labels help distinguish generated text from a supplied subtitle track. They should not be treated as decorative names for every caption option.
Check the eligibility note
Apple documents generated and multiple-language subtitle features for iOS 27 or later on iPhone 15 Pro, iPhone 15 Pro Max and iPhone 16 models or later. Its stated generated-subtitle availability includes English for the United States and Canada when the content lacks subtitles. Do not promise the feature on every iPhone or for every language and app.
Supplied accessible captions remain distinct
A programme’s SDH or closed-caption track can include edited timing and descriptions beyond ordinary dialogue. A generated option is another source with a different process. If those details matter, inspect the actual available tracks rather than assuming the new label reproduces every accessibility feature of the supplied version.
Compare without overclaiming accuracy
Use a short clear passage and inspect the wording and timing. Names, overlapping voices and difficult audio can challenge automatic text. A label tells you how the text was obtained; it is not certification of a perfect transcript or a programme’s official translated script.
Report the exact context
Include the label shown, iPhone model, iOS version, app and language choice. A missing option can be an eligibility question rather than a failed account. Keep this feature separate from general Live Captions and from browser-page translation, since those are other text paths with their own controls.

Are the generated subtitle options available on every iPhone?
