YouTube’s automatic captioning system can now describe sound effects
YouTube has long had an automatic captioning system that, thanks to Google’s machine learning advances in recent years, has gotten pretty good at automatically transcribing spoken words in a video. As the company announced today, its technology is now able to take this a step further by also captioning some of the ambient sounds like [LAUGHTER], [APPLAUSE] and [MUSIC]. For now, the automatic effects captioning is actually restricted to those exactly these three sounds. The reason for this, Google says, is that these are also exactly the sounds that most video producers manually caption right now.
