In order to accomplish speech quality evaluation tasks in an efficient and economical way, objective computational models which simulate human hearing characteristics of speech perception have been intensively researched in the past decades. Several models have already been developed and standardized in telecommunication industry to assess the listening quality of speech signals transmitted through telecommunication network or generated by voice-communication terminals. Among those standardized models, POLQA, short for Perceptual Objective Listening Quality Assessment, is the newest generation objective metrics designed to address the shortcoming and weakness existed in previous published models such as PESQ and PSQM.
