Conjunto de Regras para Desambiguação de Homógrafos Heterófonos no Português Brasileiro

This paper presents a rule-based algorithm set used to decide the reading of homographs applied in a Brazilian Portuguese Text-to-Speech (TTS) system. The proposed approach is composed of a morphosyntactic analysis, which deals with problems of homographs that belong to different part-of-speech (POS), and a semantic analysis, which deals with problems of homographs that belong to the same POS, through 107 homograph pairs, which are organized into 22 disambiguation algorithms. The algorithms were implemented and tested with three types of texts. Computer experiments show they have achieved an error rate of 1.42%, 1.40% and 1.30%, respectively.
