I am having problems with adding words with accented characters to the lexicon file. For example, using the Marta voice the work "niña" is always pronounced "n i1 nj a0" no matter what I specify in the lexicon file. Is there something specific I need to do in order to get the engine to read accented characters from the lexicon file?
Also, reading the tutorials at http://www.cepstral.com/en/tutorials/view/lexicon, all accented characters are replaced by "?" so the Spanish tutorial has sample words like "ni?a" instead of "niña." This really should be fixed.
