Go to the show or movie you’re watching, then open the Audio & Subtitles menu and switch the audio or captions from Spanish to English. On Peacock, that menu is usually in the bottom-left on web/TV and the top-right on mobile, and the English option should appear if that title supports it.

Steps

  1. Start playing the title.
  2. Open the audio/subtitle menu.
  3. Choose English for audio, subtitles, or both.
  4. Close the menu and keep watching.

If it stays in Spanish

  • Try a different title, because not every program has both languages.
  • Log out and back in, or restart the app if the setting does not stick.
  • On TV devices, the language control may appear only after playback starts.
Quick fix: if you only need English subtitles, change just the subtitle track; if you need English audio, switch the audio track instead.
TL;DR: Play the video, open **Audio & Subtitles**, and pick **English**.
