Predicting Performance of PESQ in Case of Single Frame Losses
Christian Hoene, Enhtuya Dulamsuren-Lalla · 2004
ITU’s objective evaluation algorithm PESQ predicts the quality of speech transmissions. In this work we verify whether PESQ can measure the impact of single frame losses – a source of impairment for which PESQ has not been designed. To construct samples for experimental tests, we develop a tool that controls the loss of specific frames, e.g. only important or voiced frames. We conduct subjective, formal listening-only tests to verify PESQ’s prediction performance. The human ratings correlate with PESQ at a degree of R=0.94. Given the precision of speech quality measurements we show the equality of subjective and instrumental results.
