Spanish recordings can cross regional vocabulary, pronunciation, and English code-switching within a single conversation. Set es when Spanish is dominant, use word-level playback to resolve names and short discourse markers, and preserve inverted punctuation and accents when the surrounding sentence calls for them.

What to expect from Spanish audio
Spanish spans many regional varieties, so a single es language hint sets the speech language without pretending that vocabulary and pronunciation are uniform. The practical review targets are regional vocabulary, names, inverted punctuation, and Spanish–English code-switching. Use the es hint for predominantly Spanish speech; regional vocabulary and pronunciation remain editorial review points.
Review the details that carry meaning
Code-switching, names from another language, and punctuation around discourse markers need listening context. Use word-level playback for regional vocabulary, names, inverted punctuation, and Spanish–English code-switching; a correction is accepted only when the surrounding clause and project convention support it.
