Blind listening study

Whose accent
wins?

You'll hear 20 short trials. Each one gives you two reference clips — the target accent, and the speaker's own natural voice — followed by three candidate versions of that speaker converted toward the target accent. Pick whichever one sounds closest to the target accent. Don't worry about audio quality or whether it still sounds like the same person — judge accent only.

Please wear headphones. The differences between options are subtle and easy to miss on laptop or phone speakers.

Don't be alarmed if a clip sounds familiar partway through — a few trials intentionally reuse the same audio as a shared reference point across different comparisons. It's not a copy-paste mistake; those trials are testing different things.
