1. A system for synchronizing output of audio content with textual content, the system comprising: a data store that stores textual content; an input device that obtains a location of a pointer referencing the textual content; a display device that presents the textual content; an output device that outputs audio content; and a processor in communication with the data store, the input device and the output device, the processor operative to: generate audio content based at least in part on the textual content; cause output of the generated audio content via the output device; cause presentation of the textual content on the display device; maintain synchronization of a position of the textual content presented on the display device with an associated position of the generated audio content output via the output device, wherein the associated position advances during output of the generated audio content; obtain a current location of a pointer referencing the textual content presented on the display device from the input device; determine a segment of textual content based at least in part on a difference between the current location of the pointer referencing the textual content and the position of the textual content; determine a length of time required to output audio content corresponding to the determined segment of textual content; and modify a speed at which the generated audio content is output via the output device based at least in part on the determined length of time.
