1. Handedness assessment.

Play the sounds by clicking the buttons. If your browser does not play the sound, click the embedded player below the button. If you still do not hear the sound, you need to turn on audio on your computer.

Please listen to these pairs of computer-made vowels at least twice and decide which vowel sounds clearer or more exaggerated to you. Then tell us how certain (or confident) you feel about your decision on a scale of 1~10. (1 for very uncertain, and 10 for 100% certain).
