SYSTEM AND METHOD FOR ROBUST ACCESS AND ENTRY TO LARGE STRUCTURED DATA USING VOICE FORM-FILLING

摘要

A method, apparatus and machine-readable medium are provided. A phonotactic grammar is utilized to perform speech recognition on received speech and to generate a phoneme lattice. A document shortlist is generated based on using the phoneme lattice to query an index. A grammar is generated from the document shortlist. Data for each of at least one input field is identified based on the received speech and the generated grammar.

1. A method comprising:
identifying an index of words and a phone lattice;removing insignificant units from the phone lattice, to yield a revised phone lattice;
normalizing costs in the revised phone lattice such that a cost of a best path is set to zero; generating a cost-normalized query using factors of interest, wherein the index of words is indexed by the factors of interest; and generating a shortlist of recognized speech possibilities using the revised phone lattice, the index of words, and indices contained in the cost-normalized query.
