Grapheme-Phone Transcription Algorithm for a Brazilian Portuguese TTS

摘要

This paper describes one of the aspects of an ongoing research to improve the synthetic speech quality for a Brazilian Portuguese text-to-speech synthesis system. This paper focuses on the grapheme-phone transcription algorithm. A complete set of rules for every grapheme is presented. Experimental results, obtained running the proposed algorithm through a text database, gave rise to 98,43% of accuracy rate.
