System and method of media file access and retrieval using speech recognition
First Claim
1. An embedded device for playing media files and generating a play list of media files based on input speech from a user, comprising:
- an indexer generating a plurality of speech recognition grammars, including at least one of;
(a) a first indexer generating a first speech recognition grammar based on parsed contents of a media file header of the media file; and
(b) a second indexer generating a second speech recognition grammar based on parsed categories in a file path for retrieving the media file to a user location;
a speech recognizer receiving an input speech from a user while in a selection mode; and
a media file selector comparing the input speech received while in the selection mode to the plurality of speech recognition grammars, thereby selecting the media file.

Abstract
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 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, thereby selecting the media file.
