Study of Objective Quality Evaluation for the Speech Systems
Hui Qing Huang · Dianzi xuebao · 2000
Using the LPC CD,Bark SD and Mel CD distortion measures,we experimentally study the Objective Quality Eva luation of a large number of the speech systems.The result shows that each of these measures gives better correlation between objective and subjective measurement when they are used independently to those systems.Combining their results through a weighted and average way,higher correlation coefficient can be given,we can conclude that these measures have certain validity and utility to appraise the quality of speech systems.
