Abstract

Typically, audio quality assessment uses MUSHRA (Multi Stimulus with Hidden Reference and Anchors), while speech quality assessment uses ACR (Absolute Category Rating). Since many applications are transporting both speech and music, such as mobile devices, a conversion technique between the two types of ratings would be useful. Two speech and two audio quality listening tests are compared with different content types. The results illustrate when and how the two types of measurements are consistent, complementary, and inconsistent.
