Abstract

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).

Description

technical field [0001] The present invention relates to mobile communication devices, and in particular to voice indexing and searching in mobile communication devices. Background technique [0002] Mobile communication devices, such as cellular telephones, are very common communication devices used by people of all languages. The use of the device has expanded far beyond pure voice communication. Users are now able to record notes, conversations, messages, etc. using the mobile communication device as a voice recorder. Users can also use voice to annotate content such as photos, videos and applications on the device. [0003] While these capabilities have expanded, the ability to search stored audio content on mobile communication devices is limited. Since content is difficult to navigate with buttons, mobile communication device users may find it useful to be able to quickly find voice-annotated content, stored voice-recorded conversations, notes and messages. Content...
