Abstract: Systems and methods are provided for causing aural and/or visual presentation of reference content, such as word definitions, in response to a request regarding a portion of media content during playback. In some embodiments, one or more words may be determined that may be of interest to the user from among words in a content window preceding a current playback position in the content, without the user specifying a specific word of interest. A presentation of reference content corresponding to the determined one or more words may be generated and presented aurally and/or visually in order to provide definitions, encyclopedia information, summary information, and/or other information regarding a portion of media content near the current playback position.
