One Billion Videos Captioned.. sort of

While YouTube is bragging about have one billion captioned videos, critics are pointing out that many of the automatically generated captions are wildly inaccurate.

Key to the success of this endeavor was improving our speech recognition, machine learning algorithms, and expanding our training data. There were limitations with the technology that underscored the need to improve the captions themselves. Results were sometimes less than perfect, prompting some creators to have a little fun at our expense!
