Abstract: Systems and methods for generating and using performance metadata associated with a media piece (e.g., music or video) are provided. An electronic device can monitor a user's workout performance while playing a particular media piece. Workout performance may include the user's rate of motion and/or one or more physiological metrics of the user. Based on the user's workout performance, the electronic device can create new or modify existing performance metadata associated with the media piece. In some embodiments, the performance metadata based on a particular user's workout performance in response to a media piece may be combined with collective performance metadata based on the workout performances of multiple users in response to the media piece. The combined performance metadata may then be stored as new collective metadata. Accordingly, the collective performance metadata can represent the average response to a media piece over multiple users.

Abstract: Systems and methods are provided for monitoring a user's progress towards a workout goal spanning multiple workouts and providing a workout reminder based on the progress. An electronic device can monitor the user's progress towards the goal by monitoring the user's rate of motion and/or one or more physiological parameters of the user. Based on the user's progress towards the goal, the electronic device can provide a workout reminder. For example, if a user's progress is not sufficient to achieve the workout goal, the electronic device may provide a reminder to the user. The reminder can include a visual and/or audio alert to the user, and the reminder may interrupt other functions on the device.

Abstract: 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.

Abstract: Systems and methods are provided for a graphical representation of the workout effectiveness of a playlist. A particular playlist or collection of media items can be received. A burn graph can then be generated from the playlist, where the burn graph represents the expected effort level of a user who is exercising while listening to the playlist. The expected effort level can be determined by analyzing, for example, the beats per minute, tempo, mood, brightness, or genre of the media in the playlist. Additional user information such as, for example, a user's weight, age, height, stride length, resting heart rate, data from prior workouts, user's mood, or any combination of the above, can be taken into account when generating the burn graph.

Abstract: Algorithms for synthesizing speech used to identify media assets are provided. Speech may be selectively synthesized form text strings associated with media assets. A text string may be normalized and its native language determined for obtaining a target phoneme for providing human-sounding speech in a language (e.g., dialect or accent) that is familiar to a user. The algorithms may be implemented on a system including several dedicated render engines. The system may be part of a back end coupled to a front end including storage for media assets and associated synthesized speech, and a request processor for receiving and processing requests that result in providing the synthesized speech. The front end may communicate media assets and associated synthesized speech content over a network to host devices coupled to portable electronic devices on which the media assets and synthesized speech are played back.

Abstract: Delivery and/or presentation of electronic data to a mobile electronic device in accordance with a dynamic user profile are disclosed. In one embodiment, as the user profile changes, the electronic data being delivered to and/or presented on the mobile electronic device can dynamically change. In other words, the electronic data being delivered and/or presented can be selected, customized or targeted for characteristics of the dynamic user profile.

Abstract: Improved approaches to present groups of digital assets in a dynamic, graphical manner are disclosed. The groups to be presented can be automatically formed in accordance with grouping criteria. Each of the resulting groups can then be visually represented by a set of images. The sets of images for the different groups can be dynamically visually presented in a sequential manner. The plurality of images that represent a particular group can be concurrently presented in a partial overlapped arrangement. Optionally, user interaction can affect the group(s) being presented, alter the images visually representing the group(s), or cause other navigational actions with respect to the digital assets. The presentation of the groups (e.g., clusters) can serve to assist a user in understanding what digital assets (e.g., digital media assets) are available on an electronic device. The electronic device typically permits the user to utilize (e.g., play, view, etc.) the digital assets.
