Title: Subjective Evaluation of Join Cost Functions used in Unit Selection Speech Synthesis
Authors: Vepa, Jithendra

Issue Date: Oct-2004
Citation: Proc. ICSLP2004, Jeju, Korea
Abstract: 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.
