Welcome to the questionnaire! 

After answering a few questions about yourself, you will hear two voice recordings. These will be in either in German or in Japanese. After each pair, you will be asked if the voices belong to the same person or not. Then, you will indicate on a scale how confident you are in your answer.

The survey will take about 20-30 minutes in total. 

At the end of the experiment, you will receive your personalized results showing how many voices you identified correctly.

Make sure you are in a quiet environment and use headphones, if possible. 

Starting the experiment on the next page indicates your consent to the anonymized use of your data.
