1. A computer-implemented method comprising: displaying an electronic document on a display of a computing device; determining a semantic meaning associated with one or more words in the electronic document, the one or more words being located at a specific location of the electronic document being displayed on the computing device; identifying an audio file corresponding to the semantic meaning; detecting a gaze direction of a user of the computing device, the gaze direction being relative to the display of the computing device; determining an estimated location on the display that corresponds to the gaze direction; determining that the estimated location is within a threshold distance from the specific location of the one or more words; and playing the audio file with a volume based at least in part upon the semantic meaning of the one or more words and determining that the estimated location is within the threshold distance from the specific location of the one or more words.
