This paper is emphasized on analyzing the evaluation ability of RMSE and correlation in duration prediction. RMSE and correlation, as two chief evaluation means of duration prediction models, have their own strong points and weaknesses. We have hence carried out a perceptual experiment to investigate the characteristics of these two means, both in comparing two prediction systems and in evaluating the performance of a single predictor. In analyzing the performance of a duration prediction system, we put forward a more effective approach to appraise the predicted duration and hence come to the conclusion that a duration prediction system can be improved through valid information of stress/unstress and phonologically important syllables.
