Special-domain speech synthesizer

Special application domains impose various specific limitations such as storage and vocabularies on synthesizers. This work proposes a systematic approach to develop special-domain corpus-based speech synthesizers. An optimal recording script can be generated according to configurable application requirements. Moreover, the corresponding unit inventory and synthesizer can be constructed under minimal user intervention. A route guidance example is also presented to illustrate the applicability. As more and more applications appear on small devices in intelligent environments, the proposed approach increases the development efficiency and effectiveness of speech interface.
