Thank you for your participation to this listening test. Answering to the test will last about 10 minutes.

In this form, you will be asked to answer 13 simple questions about sound samples from a Corsican traditional singing dataset. Two dimensions of the sounds are under study: naturalness and comprehensibility. Naturalness is the quality of a sound to correspond to listeners' expected standards of timber, rate, rhythm, intonation and stress. Comprehensibility refers to the degree to which a listener, provided with additional information about what the speaker is saying, recognizes the phonemes pronounced in the audio sample.

In the following questions, you will be asked to give a score 1-5 of naturalness and a 1-5 score of comprehensibility , 1 being very poor as compared to reference and 5 being as good as reference. To help you in your evaluations, a reference audio sample is given at the beginning of the test.If you have any doubts, you can go back on the previous questions by clicking "Return".  The text you will hear is an excerpt from a latin prayer and is composed of the two words "agimus tibi", sung very slowly.
