ABSTRACT:
A method for reconciling pronunciation differences between respective vocabularies of recognition and text to speech (TTS) engines in a speech application, first compares respective pronunciations of each word in the recognition engine's vocabulary with each word's pronunciation by the TTS engine, second, for each word for which the pronunciations are different, the recognition engine's pronunciation of the different word is added to an exception dictionary of the TTS engine. Before adding the recognition engine's pronunciation of the different word to the exception dictionary, each different word is tested for form consistent with the exception dictionary. Each different word which is not consistent in form with the exception dictionary is converted to a suitable form prior to being added to the exception dictionary. The pronunciations are compared by comparing baseforms of the pronunciations.
