Abstract: A system is provided for enabling voice-enabled selection and execution for playback of media files stored on a media content playback device. The system includes a voice input circuitry and speech recognition module for enabling voice input recognizable on the device as one or more voice commands for task performance; a push-to-talk interface for activating the voice input circuitry and speech recognition module; and a media content synchronization device for maintaining synchronization between stored media content selections and at least one list of grammar sets used for speech recognition by the speech recognition module, the names identifying one or more media content selections currently stored and available for playback on the media content playback device.

Abstract: A system for voice-enabled location and execution for playback of media content selections stored on a media content playback device has a voice input circuitry for inputting voice-based commands into the playback device; codec circuitry for converting voice input from analog content to digital content for speech recognition and for converting voice-located media content to analog content for playback; and a media content synchronization device for maintaining at least one grammar list of names representing media content selections in a current state according to what is currently stored and available for playback on the playback device.
