Abstract
This invention relates to a method of defining an optimised set of test sequences for use with a packet based perceptual quality evaluation processor associated with an edge-device that receives packets containing speech data and converts said packets to a speech signal, the method comprising the steps of: defining a set of quality targets which should be produced when a test sequence of packets is processed by the edge-device; determining a value for a degradation parameter for each quality target wherein a test sequence having a degradation according to said value will substantially produce said quality target when said test sequence is processed by the edge-device.
