Abstract
This proposal presents performance indices and search criteria for the text script generation in the design of corpus-based TTS systems. Based on our criteria a new search method is presented to solve the text selection problem more systematically and efficiently, unlike previous researches either concentrated on covering rate or on hit rate. By control a weighting factor, the covering rate of unit types can be increased to improve the robustness of the TTS system. Finally, the scalable and controllable design of the multi-stage search can produce various kinds of text scripts ideally suitable for the requirement of various kinds of corpus-based TTS systems.
