Gaudi

Google Audio Indexing (Gaudi) is a new technology from Google that allows users to better search and watch videos from various YouTube channels. It uses speech technology to find spoken words inside videos and lets the user jump to the right portion of the video where these words are spoken. Google Audio Indexing is a showcase for speech technology. Political videos and election materials are a special case of broadcast news content, a domain that has received a lot of academic and industry attention and is known to perform well. By making the technology available to a wide audience, we hope to both offer a useful service and learn what our users think of this new technology.

Google Audio Indexing uses speech technology to transform spoken words into text and leverages the Google indexing technology to return the best results to the user.
The returned videos are ranked based — among other things — on the spoken content, the metadata, the freshness.
We periodically crawl the YouTube political channels for new content. As soon as a new video is uploaded to YouTube, it is processed by our system and made available in our index for people to search.
