The aim of this study is to develop a speech synthesis system based on the speech production process and to create related applications by taking the advantage of its flexibility. A speech synthesis simulation system developed here allowed us to evaluate the adequate ranges of related parameters. Based on the results, a system with GUI (graphical user interface) has been developed for an automatic parameter adjustment function. Moreover, a vocal tract mapping interface has been developed as a signal measurement converter. This interface is applicable to a vowel sound generator driven by an input signal through the vocal tract shape.
