Computerised versions of US President Barack Obama and rival Mitt Romney have been created before the election on Tuesday.
The interactive characters were created by Cereproc, a company associated with the University of Edinburgh.
The talking heads are a combination of animation and the latest voice technology. As a result the speech generated imitates both of the presidential candidates.
Dr Matthew Aylett, of the University of Edinburgh's School of Informatics, said: "Although creating virtual presidential candidates was a bit of topical fun, this exercise also has a very real scientific objective.
"By using content, speech and images, we wish to create a sense of character that can be used in the future to make virtual people more engaging and improve their usability."
Cereproc previously created a similar online representation of President George W Bush known as the Bush-o-matic.
Americans go to the polls on Tuesday to decide if Mr Obama, a Democrat, will enjoy another four years in the White House or whether Republican Mitt Romney’s economic plans will propel him into the Oval Office.
