Abstract

In this study evaluation of two self-learning methods (MBL and TBL) on European Portuguese grapheme-to-phone conversion is presented. Combinations (parallel and cascade) of the two systems were also tested. The usefulness of syllable information is also investigated. Systems with good performance were obtained both using a single self-learning method and combinations. Best performance was obtained with MBL and the parallel combination. The use of syllable information contributes to a better performance in all systems tested.
