In this paper, we describe a speech re-synthesis tool using the fundamental frequency (F0) generation model proposed by Fujisaki et al. and STRAIGHT, designed by Kawahara, which can be used for listening experiments by modifying F0 model parameters. To create the tool, we first established a method for automatically estimating F0 model parameters by using genetic algorithms. Next, we combined the proposed method and STRAIGHT. We can change the prosody of input speech by manually modifying the F0 model parameters with the tool and evaluate the relation between human perception and F0 model parameters. We confirmed the ability of this tool to make natural speech data that have various prosodic parameters.
