Live Caption helps with spoken audio; it does not turn every silent interface label into verified text. Keep captioned speech and the written screen in separate notes when they seem to disagree.
Check feature availability
On supported devices and languages, Live Caption captions speech from device audio. Find it through Settings search or the volume controls. Availability varies; consult device support if missing. The caption box can be dragged when it obscures content. See Google's Live Caption instructions.
Use a short public audio sample for a reading comparison. Do not assume a silent label will produce a caption, and do not perform an account action simply to generate audio. The comparison needs a visible text item and a spoken passage, not a transaction or private call.
Keep a two-part hypothetical record
Imagine an app showing a button labelled “Room B” while a voice says “Open Room A”. Suppose the caption also reads “Open Room A”. Your record should have two entries: “Visible button: Room B” and “Captioned speech: Open Room A”. The caption did not rename the button.
If replaying the public sample is possible without another action, listen again and compare the caption. Keep the discrepancy unresolved if the two sources still differ. Do not call the caption an official correction, and do not assume it transcribes every spoken word perfectly. An unspoken identifier cannot be checked by listening alone.
Handle obstruction and missing output
If the caption box covers the written label, move it using the documented drag interaction and reread the complete label. Seeing only its first word is not enough for the comparison. If no caption appears, note that result rather than concluding that the app contains no speech.
The useful outcome is a record of which material was visible, which was captioned and what remains uncertain. Our unclear-screen reading checklist offers related context; neither that checklist nor captioning verifies an app's hidden rules or operating status.
