EchoLens use policy

EchoLens contains identifiable human speech. A voice is biometric, and a
speaker with a known reference sample could in principle be re-identified.
Participants were never asked to state names or other direct identifiers. All
515 participants gave informed
consent to public release of their recordings through public research
repositories (Stanford IRB protocol #77233). Your access is conditioned on the
commitments below.

You may use EchoLens for non-commercial research on the fairness,
robustness, and evaluation of speech and audio-language systems, including
training research models, consistent with CC BY-NC 4.0.

You may not

• attempt to identify, contact, or infer the legal identity of any speaker;
• use the recordings for speaker recognition, speaker verification, voice
  biometrics, voice cloning, or synthetic voice generation;
• use the recordings in production or deployed voice systems;
• treat any recording or demographic label as evidence of a speaker's actual
  identity, race, gender, or national origin;
• re-host the audio in any ungated venue;
• use EchoLens for any commercial purpose without prior written permission
  from the authors.

Demographic labels are self-reported and support a bounded Black/White ×
Female/Male audit design. They are not ground truth about any individual.

Participants retain the right to withdraw. On a withdrawal request the
maintainers will remove the affected recordings and issue a new version; you
agree to delete withdrawn recordings from your copies on notification.
