Welcome & Consent

In this study you will listen to pairs of short voice recordings. For each pair you'll judge how similar the two voices sound, whether you think they are the same speaker, and how confident you are.

• Each clip can be replayed up to 3 times.
• There are no right or wrong answers — go with your perception.
• The session takes roughly 10–15 minutes.

I have read the instructions and consent to take part.
