Subjective Evaluation Of Join Cost Functions Used In Unit Selection Speech Synthesis

Research output: Chapter in Book/Report/Conference proceedingConference contribution


In our previous papers, we have proposed join cost functions derived from spectral distances, which have good correlations with perceptual scores obtained for a range of concatenation discontinuities. To further validate their ability to predict concatenation discontinuities, we have chosen the best three spectral distances and evaluated them subjectively in a listening test. The unit sequences for synthesis stimuli are obtained from a state-of-the-art unit selection text-to speech system: rVoice from Rhetorical Systems Ltd. In this paper, we report listeners preferences for each of the three join cost functions.
