METHOD AND APPARATUS FOR LANGUAGE INDEPENDENT VOICE INDEXING AND SEARCHING

摘要

A method and apparatus for language independent voice searching in a mobile communication device is disclosed. The method may include receiving a search query from a user of the mobile communication device (4200), converting speech parts in the search query into linguistic representations (4300) which covers at least one languages, generating a search phoneme lattice based on the linguistic representations (4400), extracting query features from the search phoneme lattice (4500), generating query feature vectors based on the extracted features (4600), performing a coarse search using the query feature vectors and the indexing feature vectors from the indexing database (4700), performing a fine search using the results of the coarse search and the indexing phoneme lattices stored in the indexing database (4800), and outputting the fine search results to a dialog manager (4900).
