Abstract

This work presents a method of objective quality assessment of telephony band codecs (300 - 3400 Hz) that assembles the main characteristics of the methods found in the literature, named" Medida Objetiva de Qualidade de Voz" (MOQV). Ananalysis of its performance is presented based on a set of experiments available in a database of the International Telecommunication Union (ITU). Such performance analysis provides an ample characterization of the method allowing the determination of the circumstances where its use is adequate, besides providing subsidies to its use face to several practical situations.
