People were begging for this kind of thing during the 2012 presidential campaign, but it looks like technology was about a year too late. Still, this is really cool:
Truth Teller is a news application built by the Washington Post with funding from a Knight News Prototype grant. The goal of Truth Teller is to fact check speeches in as close to real time as possible. The three-month prototype built by the Post is an enormous step in that direction.
The Truth Teller prototype was built and runs with a combination of several technologies — some new, some very familiar. We’ve combined video and audio extraction with a speech-to-text technology to search a database of facts and fact checks. We are effectively taking in video, converting the audio to text (the rough transcript below the video), matching that text to our database, and then displaying, in real time, what’s true and what’s false.
You can see TruthTeller in action over here. It's not much to look at yet, but I have high hopes for this thing by the time 2016 rolls around.
