Abstract
An approach for automatically determining the accuracy of a pronunciation dictionary in a speech recognition system involves comparing an expected pronunciation representation for a particular word from a pronunciation dictionary to one or more actual pronunciations of the particular word. An accuracy score for each of the phonemes that constitute the pronunciation of the particular word is determined from the comparison of the expected and actual pronunciations for the particular word. The accuracy score is evaluated against specified accuracy criteria to determine whether the expected pronunciation for the particular word satisfies the specified accuracy criteria. If the expected pronunciation does not satisfy the specified accuracy criteria for the particular word, then the expected pronunciation for the particular word in the pronunciation dictionary is identified as requiring updating. Manual or automated update mechanisms may then be employed to update the identified expected pronunciation representations to reflect the actual pronunciations.
