A training clip in a desktop player may have no usable captions of its own. Windows Live captions can provide a local reading aid across applications, but first check the language, audio route and what you expect to keep afterwards.

The feature requires Windows 11 version 22H2 or later. Press Windows+Ctrl+L or open Settings, Accessibility, Captions. The first setup asks for consent and downloads language files. After setup, caption generation can work offline. Translation has additional Copilot+ PC requirements; do not assume ordinary captioning includes it.

Prove the audio path with a short sample

Play familiar speech and watch the caption window. Microsoft says Live captions follows the default sound output device. If a headset change leaves the window blank, compare that default with the device carrying the audio before changing unrelated microphone settings.

Position the captions where you can read them without covering the relevant demonstration. Test a passage containing a name, a number and a pause. These details reveal recognition mistakes that a generally fluent sentence can conceal.

Include microphone audio is optional and starts off. Enable it only when you intend to caption nearby speech. Computer playback takes priority when it overlaps microphone speech.

Separate a reading aid from a record

Microsoft processes these captions on the device and does not store the generated captions. If you need an enduring transcript, arrange a suitable recording or transcription workflow separately and obtain any required permission.

Use the captions to follow the material, then verify consequential details against the speaker or original document. Music and other non-speech sounds are not a dependable part of this output. Before a session where captions are essential, repeat the short test with the actual headset, language and application rather than discovering the difference after the session starts.
