If you were glued to your computer during the live broadcast of the Google I/O keynote yesterday morning, you might have noticed a new feature accompanying an otherwise recognizable YouTube video. The online video provider used this morning's conference kickoff as the springboard for its live captioning feature, which brings human input to the transcription process. According to Google's Naomi Black, a team of stenographers banged out translations during this morning's keynote. The resulting captions were then displayed on the conference floor and delivered by an "open source gadget" to the I/O YouTube channel. This new feature apparently prevents the inaccuracies experienced using Google's automatic captioning function, which, if you'll recall, provided us with at least a couple hearty chuckles when we took it for a spin. The code behind the new live captions will be available to YouTube's partners and competitors on Google Code. You can check out tomorrow's keynote to see how the humans fare.
