However, there lacks still a robust metric quantifying the perceptual quality of a Skype call. The widely-used PESQ (Perceptual Evaluation of Speech Quality) falls short of modeling super-wideband calls, which are characteristics of SILK Skype's codec made public in 2011. Towards a robust QoE (Quality of Experience) metric for VoIP call analysis, we propose a model, referred to as WF-Regression model, to capture the call rate and perceptual quality relationship. The model is shown through a user study that it is robust, R-square = 0.9990 and outperform PESQ modeling the quality of Skype calls, error ratio = 3.68% vs. 14.59%.<\/jats:p>","DOI":"10.1145\/2377677.2377779","type":"journal-article","created":{"date-parts":[[2012,9,25]],"date-time":"2012-09-25T23:48:08Z","timestamp":1348616888000},"page":"521-526","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":5,"title":["Measuring the perceptual quality of Skype sources"],"prefix":"10.1145","volume":"42","author":[{"given":"Chien-nan","family":"Chen","sequence":"first","affiliation":[{"name":"National Taiwan University, Taipei, Taiwan Roc"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Cing-yu","family":"Chu","sequence":"additional","affiliation":[{"name":"National Taiwan University, Taipei, Taiwan Roc"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Su-ling","family":"Yeh","sequence":"additional","affiliation":[{"name":"National Taiwan University, Taipei, Taiwan Roc"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hao-hua","family":"Chu","sequence":"additional","affiliation":[{"name":"National Taiwan University, Taipei, Taiwan Roc"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Polly","family":"Huang","sequence":"additional","affiliation":[{"name":"National Taiwan University, Taipei, Taiwan Roc"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"320","published-online":{"date-parts":[[2012,9,24]]},"reference":[{"key":"e_1_2_1_1_1","volume-title":"ITU","author":"U-T","year":"2006","unstructured":"IT U-T Recommendation P.10\/G.100.
