1. A system for synchronizing output of translated content during consumption of base content, the system comprising: one or more data stores that store: a base content; translated content corresponding to the base content, wherein the translated content differs from the base content by at least one of language, dialect, or alphabet; and content synchronization information that identifies: one or more positions within the base content, and for each of the one or more positions within the base content, a corresponding position within the translated content; at least one input device configured to at least receive user interaction information during consumption of the base content, the user interaction information relating to interaction by a user with the base content during consumption of the base content; at least one output device configured to at least output the base content and the translated content; and at least one processor in communication with the one or more data stores, the at least one input device, and the at least one output device, the at least one processor configured to at least: cause output of the base content via the at least one output device; analyze the user interaction information to detect a current position of consumption of the base content, wherein the current position of consumption advances during consumption of the base content; determine that the content synchronization information identifies a first position within the base content that corresponds to the current position of consumption of the base content; identify, based at least in part on the content synchronization information, a first position within the translated content that corresponds to the first position within the base content; cause synchronization of output of the base content and output of the translated content from the current position of consumption of the base content and the first position within the translated content; and maintain, based at least in part on the content synchronization information, synchronization of the output of the base content and the output of the translated content as the current position of consumption of the base content advances during consumption of the base content.
2. The system of claim 1 , wherein the at least one processor is configured to at least maintain synchronization of the output of the base content and the output of the translated content by repeatedly: determining that the current position of consumption has advanced during consumption of the content; determining that the content synchronization information identifies a next position within the base content that corresponds to the current position of consumption as advanced; identifying, based at least in part on the content synchronization information, a next position within the translated content that corresponds to the next position within the base content; and causing synchronization of the output of the base content and the output of the translated content from the current position of consumption of the base content as advanced and the next position within the translated content.
