Automatic generation of pronunciation lexicons for Spanish

Abstract

In this paper a method for the automatic generation of pronunciation lexicons including multiple word pronunciation is presented. This method is based on the application of a set of rules for grapheme-tophone conversion for Mexican Spanish. The generation of multiple word pronunciations is based on the introduction of pronunciation variants by applying allophonic rules. The performance of a speech recognition system using a pronunciation lexicon with and without multiple word pronunciations is also presented.
