Activating Live Captions on an iOS Device
Live captions on an iOS device can only be activated in the device settings.
Go to Settings > Accessibility > Live Captions (Beta).
Turn on Live Captions, then tap Appearance to customize the text, size, and color of the captions.
Live Captions in Listen EVERYWHERE App
With live captions enabled, live captions are automatically generated when the device detects incoming speech from audio channels. Simply open the Listen Everywhere app and select a channel; the captions will appear regardless of your device’s volume. Captions are not saved anywhere and once they disappear from the screen, they are gone.
