1. To participate in this survey you must be a native American English speaker located in the U.S. The survey will take around 10 minutes to complete.

You will be listening to 33 sets of audio samples. In each set, there are two audio recordings (A and B) of the same text. Please listen to the audio clips carefully, compare each audio with the reference, and then

Rate how natural is B compared to A on a scale of -6 to 6 with 6 indicating that B is much better than A. Here, naturalness includes whether you feel the speech is spoken by a native American English speaker from a human source, as opposed to being synthesized by a computer.

There are some audios for checking your attention through the survey. If a certain number of the scores are rated unreasonably, you will not be paid. So, listen to the audio carefully and do not fill out the survey randomly. *This question is required.

I have read the above purpose of the study, and understand my role in participating in the research. I volunteer to take part in this research. I understand that I may refuse to participate or withdraw from participation at any time. The investigator may withdraw me at his/her professional discretion. I certify that I am 18 years of age or older and a native english speaker and freely give my consent to participate in this study.
