Read the edition label before opening the episode
The publisher’s Prime Video article says English-dubbed versions are labelled Dubbed, while the original-language version is identified with English Subtitles following the programme title. That is a catalogue selection distinction. If the spoken language is unexpected, return to the programme listing and inspect its edition label before repeatedly changing a caption control inside the same episode.
Match the series and season in both editions
The support page gives paired examples, including A French Village, Babylon Berlin and The Bridge. Use the exact series, season and edition to make the comparison. A familiar poster can lead to the dub when the viewer expected original speech. Choosing a different edition should not be confused with changing the account’s general navigation language or choosing a different episode number.
Keep captions and dubbing as separate needs
A dub changes the spoken presentation; subtitles provide text alongside the original-language presentation described in this help. A household may prefer one or the other for different reasons. Decide that requirement first, then check the actual listing and player options. The provider’s separate article about captions remaining visible should not be used to infer that an English dub and an original-language edition are the same video item.
Use the correct platform support for account issues
This workflow applies to the MHz Choice channel on Prime Video. The article directs Amazon account questions to Amazon support. A direct MHz Choice subscription or another partner route should be checked through its own instructions. Preserve the precise title and edition when reporting a mismatch; a general statement that subtitles are wrong gives support less information about which of the paired programmes was selected.

Will changing captions always change the spoken language?
