Ask where the words came from
The current iPhone guide identifies generated subtitle labels separately from supplied tracks. That distinction matters when evaluating a programme: a device-generated transcription is not evidence that a service provided authored captions.
The same visual location can conceal different origins. Inspect the selected label and the relevant system preference rather than deciding from appearance alone.
Keep language operations distinct
Transcription converts speech into text in the same language. Translation presents another language and can introduce an additional interpretation step. A conventional supplied caption track can include speaker and non-speech information that a speech transcription may not capture equivalently.
These are task differences, not a universal ranking. The viewer's required information and the actual result determine usefulness.
Use a realistic assessment
Check a familiar passage with names, a speaker change and an audible non-speech event where relevant. Note omissions or wrong words without publishing a protected transcript. Confirm the selected programme edition and language.
A successful easy line is insufficient evidence for an entire title, live event or catalogue. Generated text accuracy and feature availability remain qualified in Apple's documentation.
Read automatic behaviour carefully
Text can appear after muting or skipping back in supported conditions. That event can result from a preference rather than a newly supplied track. Record the trigger and origin label separately.
If the user needs a stable authored track, ask the legitimate provider whether one exists for the exact item instead of assuming automatic display answers the question.
Keep the conclusion precise
A useful record says a Transcribed option was used on a particular device and passage, or names the actual supplied track. It does not say the whole service is captioned based on device-generated text.
No accuracy or accessibility conformance test was performed here. This explanation follows current supported iPhone feature descriptions and does not promise those controls in every app, language or region.
Keep a provider question explicit
Ask whether the exact programme includes an authored caption or subtitle track, its language and whether it includes relevant sound information. Do not let a device demonstration replace that answer. Generated text may still be useful, but its origin and assessed limitations belong in the viewing decision. A result on one supported model is not a catalogue-wide or all-device accessibility promise.

Scope notes distinguish published documentation, supplied information and editorial methods. They do not report a hands-on service test.
