In this paper, the performance of the standard instrumental quality prediction algorithm ITU-T P.563 is reported based on the 2007 and 2008 Blizzard Challenge speech data. The algorithm, which is optimized for natural speech, is shown to obtain poor correlation with subjective quality ratings. In an attempt to improve instrumental quality prediction performance for the Blizzard Challenge, modifications to the algorithm are proposed. In particular, a novel regression tree mapping is proposed… CONTINUE READING
