12. A system for manipulating electronic multimedia content, the system comprising: a data storage device storing instructions for manipulating electronic multimedia content; and a processor configured to execute the instructions stored in the data storage device for: generating a speech model, a non-speech model, at least one speaker model of an individual speaker, and a non-speaker speech model; receiving electronic media content over a network; extracting an audio track from the electronic media content; detecting speech segments within the extracted audio track based on the speech model and the non-speech model, the speech segments containing speech from at least one of a plurality of speakers; detecting a speaker segment within the detected speech segments based on the speaker model and the non-speaker speech model, the speaker segment containing speech from the individual speaker; calculating a first probability of the detected speaker segment involving the individual speaker based on the at least one speaker speech model and the non-speaker speech model; determining a ranking or filtration of the electronic media content relative to other electronic media content based on the first probability of the detected speaker segment; detecting a face within a part of the electronic media content corresponding to the detected speaker segment and calculating a second probability of the detected face being a face of the individual speaker; and adjusting the ranking or filtration of the electronic media content based on the second probability.
