Please rate the following waveforms for

1. Naturalness : Naturalness of synthesized wave on 5 point scale. (Bad->Excellent)
2. Similarity : Similarity of synthesized wave with target wave on 5 point scale (Completely Different->Very Similar)
* If you want to know more about MOS and how to perform test please read the instructions below.

Every dataset below contains 30 waveforms, so each one will take about 5 minutes to complete. Please use headphones while listening to the waveforms. Rate these according to your time avaibility. Thank you for the help.

What is Mean opinion score ?

(MOS) is a measure used in the domain of Quality of Experience and telecommunications engineering, representing overall quality of a stimulus or system. The Mean Opinion Score Values are taken in whole numbers, the numbers are quite easy to grade. Similarity Score Between two waveforms

How Are MOS Tests Conducted?

A certain number of people are sat and are made to hear some audio. Each one of them gives a rating from within 1 to 5. Then an arithmetic mean (average) is calculated, giving the Mean Opinion Score.

High Quality Headphones are used when listening to the waveforms to clearly distinquish between synthesized and target wave.
