November 13, 2009  EP&T Magazine

AGILENT cdma200 perceptual evaluation of speech quality (PESQ) measurement functionality for its 8960 wireless communications test set helps wireless engineers enhance the end-user experience by providing an objective measurement of audio quality in digitally vocoded voice. Implementations of vocoder algorithms are designed to provide higher-quality voice at lower data rates. Sensitivity and transmitter quality of a mobile handset affects vocoder performance, and this determines the voice quality heard by the user.
