1. A system comprising: one or more processors; one or more computer-readable media; and one or more modules maintained on the one or more computer-readable media, which when executed by the one or more processors, cause the one or more processors to perform operations comprising: receiving a content item from a content source; segmenting the content item using a first segmenter to generate a first segmented content item; segmenting the content item using a second segmenter configured for use on a portable electronic device to generate a second segmented content item; comparing the first segmented content item to the second segmented content item to identify differences in segmentation of the first segmented content item and the second segmented content item; associating a segment boundary hint with the content item, wherein the segment boundary hint corresponds to an identified difference in the segmentation of the first segmented content item and the second segmented content item; receiving, from an electronic device, a request to access the content item; and sending, to the electronic device, the content item and the segment boundary hint in response to the request.
