SYSTEM AND METHOD OF MEDIA FILE ACCESS AND RETRIEVAL USING SPEECH RECOGNITION

摘要

An embedded device for playing media files is capable of generating a play list of media files based on input speech from a user. It includes an indexer generating a plurality of speech recognition grammars. According to one aspect of the invention, the indexer generates speech recognition grammars based on contents of a media file header of the media file. According to another aspect of the invention, the indexer generates speech recognition grammars based on categories in a file path for retrieving the media file to a user location. When a speech recognizer receives an input speech (404) from a user while in a selection mode, a media file selector compares the input speech received while in the selection mode to the plurality of speech recognition grammars (410), thereby selecting the media file (418).
