In this work we propose the calibrated-mean-opinion-score (CMOS), which accounts for varying levels of precision and bias across subjects in a listening test. We adopt the Bayesian statistical framework, where the hyper-parameters of priors are learned via empirical Bayes, and the posterior is appro...
