Exactly eight ratings and four preferences. No free text or identity profile.

Audio generation V4 · retained failure

The earlier 24-file set remains offline after objective screening exposed unacceptable non-speech outputs. Its failure receipt stays public so the bad result does not disappear.

The failed WAVs, players, and response flow remain quarantined.

How it works

Listen, compare and give feedback.

  1. 01

    Prepare

    Be 18 or older, find a quiet place, use a comfortable volume, and read the short consent information.

  2. 02

    Listen with roles hidden

    Finish A and B in each pair. The page never tells you which route made either clip.

  3. 03

    Make 12 decisions

    Rate all eight clips from 1–5 and make four A/B/tie choices. There is no inferred default.

  4. 04

    Submit once

    One complete pseudonymous response is stored after the anti-abuse check. Close the page before then to stop.

Release boundary

What the feedback can tell us.

The K7 release binds the participant task to its exact WAV identities, qualification receipt, operator review, and rights receipt. Accepted responses remain a voluntary convenience sample and cannot establish population preference, scientific MOS, model quality, superiority, or state-of-the-art capability.

Formal listening research remains a separate, held governance path. A formal study will appear here only after its publication rights, participant information, research governance, collection controls, and evidence contract are ready.
