      abstract = {This book evaluates the impact of relevant factors  affecting the results of speech quality assessment studies  carried out in crowdsourcing. The author describes how  these factors relate to the test structure, the effect of  environmental background noise, and the influence of  language differences. He details multiple user-centered  studies that have been conducted to derive guidelines for  reliable collection of speech quality scores in  crowdsourcing. Specifically, different questions are  addressed such as the optimal number of speech samples to  include in a listening task, the influence of the  environmental background noise in the speech quality  ratings, as well as methods for classifying background  noise from web audio recordings, or the impact of language  proficiency in the user perception of speech quality.  Ultimately, the results of these studies contributed to the  definition of the ITU-T Recommendation P.808 that defines  the guidelines to conduct speech quality studies in  crowdsourcing.},
