ABSTRACT:
A method and system for providing user access to complex information through interactive voice dialog. The computerized method includes the provision of a memory and storage in the memory of a plurality of selected words which may be recognized in predetermined phrases and dialogue contexts when spoken by users. A voice template is further stored in memory having selected information slots in corresponding frames. Each of the slots and frames is adapted to be continuously filled by recognized words. User speech utterances are initiated for receipt by the computer which requests complex information or responds to generated queries. By continuously receiving and comparing the user speech utterances to the stored plurality of selected words, slots and frames of the voice template are filled. Based on the context of the interactive dialogue and the extent of recognized vocabulary words, responsive speech segments are generated which provide the requested complex information or, alternatively, request additional information necessary to provide a full response to the user.
