<p>The invention improves the grapheme-to-phoneme alignment quality introducing a first preliminary alignment step, followed by an enlargement step of the Grapheme-set and phoneme-set, and a second alignment step based on the previously enlarged grapheme /phoneme sets. During the enlargement step are generated grapheme clusters and phoneme clusters that becomes members of a new grapheme and phoneme set. The new elements are chosen using statistical information calculated using the results of the first alignment step. The enlarged sets are the new grapheme and phoneme alphabet used for the second alignment step. The lexicon is rewritten using this new alphabet before starting with the second alignment step that produces the final result.</p> |
