Voice-dialog system for automated output of information

摘要

A voice-dialog system outputs information, in particular a telephone number. An alphabet-identifier identifies an utterance which is spelt out by the user and selects utterances that can be spelt in a similar manner from a plurality of predetermined utterances; an utterance-identifier compares the utterance input by the user with the utterances selected by the alphabet-identifier and supplies at least one utterance for output to the user. A lexicon operates on-line and stores orthographic-phonetic information for the plurality of predetermined utterances which the alphabet-identifier, the utterance-identifier and a synthesizer can access in real time.
