A system and method for providing automated generation of program groups used in shuffled playback. The playback system acquires "content information" concerning programs on subject media, and generates shuffled playback groups by comparing the content information to user entered "desired-group information". In one illustrative embodiment the content information is included on the media themselves. In a second illustrative embodiment, the content information is included in a database.

Playback list creation for digital programs in a digital device utilizes navigation path used to locate a particular digital program in a hierarchally-ordered grouping of digital programs, the grouping based on organization parameters of the digital program. The playback list is created from digital programs within the navigation path used to reach the selected digital program. The playback list may be shuffle-played or played in order. Playback of a different digital program causes changes to the navigation path, which then changes the playback list. In an MP3 player, for example, ID3 tag attributes are used as organization parameters to provide hierarchal grouping of digital audio files.

This invention is directed to an audio menu provided in an electronic device having no display. The electronic device can further include an input interface having only a single sensing element (e.g., a single button) for controlling audio playback of the device and for accessing and controlling the device audio menu. In response to a particular input detected by the single sensing element, the electronic device can enable an audio menu mode and play back audio clips associated with different menu options. The user can provide selection instructions using the single sensing element during the playback of an audio clip to select the menu option associated with the played back audio clip. In some embodiments, the audio menu can be multi-dimensional (e.g., the device plays back audio clips for sub-options in response to a selection of a menu option). Suitable menu options can include, for example, groupings of audio (e.g., playlists), options to toggle (e.g., a shuffle option), or options associated with particular metadata tags associated with audio available to the device.

A video or audio play-back apparatus has a variable random play option to control a degree of randomnees of the selections made from a play list.

The embodiment of the invention relates to the field of intelligent loudspeaker technology, and discloses a music random playback method and an intelligent loudspeaker.

Through the implementation of the embodiment of the invention, the music matched with the current environment information can be intelligently selected to play.

An electronic device can play back media items using a random playback mode. To ensure that related media items are played back in a proper order (e.g., live music is played back in concert order), the electronic device can define metadata or other data coupling related media items in a predefined or preset sequence. For example, related media items can include metadata tags identifying the previous and next media items to play back in the sequence. As another example, the electronic device can store a listing of media items of a sequence and the order in which to play them back. When the electronic device reaches a media item that is part of a preset sequence during random playback, the electronic device can identify at least the subsequent media items in the sequence, and insert the subsequent media items in the playback queue. The electronic device can then play back the entire sequence before moving to the next media item in the playback queue.

The present invention relates to a method for song searching by voice, especially the method with which users can complete settings and then start searching, so that the users' voices of search conditions will be acquired to make voice recognition, and the recognition results will be compared with the instruction data and song attribute data in the voice recognition database to obtain comparison data. If the comparison data do not correspond with the preset conditions, the next search condition generated from the comparison data will be broadcast with voice, and the users are allowed to speak out the next search condition to make comparisons of search conditions in the next process. If the comparison data correspond with the preset conditions, one or more song files will be read according to the comparison data and will be given a preview. With this method in hand, the users will not touch buttons or knobs by mistake, do not need to spend time in searching for song files one by one, and do not need to free one or both of their hands to press the buttons or knobs, either. Besides, the users can decide on such matters as search conditions, initial position of previews, whether to play immediately after choices are made, preview period, sequential or shuffle play, etc, thus promoting convenience for users in searching for songs and meeting preferences and needs of different users.
