ABSTRACT:
Empirically derived models are used to relate user perception to objectively measurable characteristics, under a criterion of nearly perfect co-variance between predicted MOS values and the variations in the values of the objectively measurable characteristics. In the example context of evaluating packet switched telephony service, the present invention eliminates the need to perform subjective tests to characterize each combination of codec type and transmission protocol.
