Audio language, subtitles and menu language are separate choices. To get the combination you want, open the program's playback controls and check the available audio and caption tracks. Changing the app's menus alone will not necessarily change what you hear.
A simple test with two favorite programs is more useful than a service describing itself as “bilingual” without saying which tracks it supplies.
How do I change the spoken language?
Start an episode or live program you can access, then look for its audio control. Choose from the tracks actually offered and listen to confirm the change. If the desired language is absent, note that result before troubleshooting the television itself.
Next, select captions or subtitles separately and check their language and readability. Roku's feature-help page explains the distinction between app controls and device settings. Use the control that changes the chosen program.
For your notes, keep four columns: app and title, menu language, spoken audio, and written captions. That prevents one successful setting from being mistaken for a complete language setup.
Why do my language preferences keep changing?
Close and reopen the app, then try a second title. The options may differ by program, and the app may store preferences in a way that depends on its account or profile controls.
If profiles are available, test the one the viewer will actually use. Record whether a setting persists, returns to a default or simply is not offered by the second title. Repeatedly changing the home network will not answer a profile or track-selection question.
What should a mixed-language household check?
Ask each viewer about spoken audio and captions separately. Someone may prefer familiar audio with captions for clarity; another may want translated text. Use the programs they genuinely watch to verify those choices.
77.2% of Miami residents aged five or older spoke a language other than English at home in 2020–2024. The statistic includes languages collectively; choose from your household's preferences rather than assuming one language fits every resident.
Write a short instruction card with the app name and the exact menu labels that lead to the relevant controls. If someone changes a setting while helping, ask them to note it for the next viewer.
What should I ask before subscribing?
Name the exact programs, language combinations and TV model that remain unverified. Ask which official route supplies them and whether live and on-demand viewing differ. Keep unresolved answers visible instead of replacing them with a channel count.
A media player cannot create an original audio track missing from the program. The useful outcome is a small list of verified combinations, known gaps and a repeatable way for each viewer to choose their settings.
