Patent attributes
One or more words at a specified location in an electronic document can be identified. The identified one or more words can be analyzed to determine one or more semantic meanings associated with the words. An audio clip (i.e., audio file, audio element) associated with or corresponding to (the semantic meaning(s) of) the one or more words can be searched for in an audio database. The search for the audio clip associated with the one or more words can utilize an index that specifies the associations between words and audio clips. In some embodiments, the audio clip can be played when an estimated location of where the user is reading is at or near the specified location of the one or more words. In some embodiments, the audio clip can be played when it is calculated that the user is reading the one or more words at the specified location.
