The quality of voice over Internet protocol (VoIP) is typically measured by mean opinion score (MOS) that significantly varies in wireless environments. Several approaches have been proposed to evaluate the MOS values of voice paths. However, these solutions require extra servers/gateways to conduct heavy computation for MOS measurement of VoIP calls. We propose two MOS measurement procedures for mobile devices. In our approach, a simple program is installed in each of the mobile devices (through an app-store like mechanism). In the perceptual evaluation of speech quality (PESQ) MOS measurement procedure, a lightweight real-time table lookup solution significantly reduces the computation time of PESQ MOS measurement from 315.4 s to 3 s. In the E-model MOS measurement procedure, the E-model MOS value can be accurately computed in 5.35 s.
