GAUDI: Google Audio Indexing

Wednesday, September 17, 2008

GAudi is short for Google Audio Indexing, and it’s the latest experiment to be added to the Google Labs. This service lets you do a text search for spoken words in videos of YouTube’s US politicians channels. The functionality was previously already available as part of an iGoogle gadget.

Searching for videos

To find a set of videos, simply type a query in the search box and press the "Search videos" button. The results of your search will appear in the left column. You can refine your search using channel filters, the active filter showing in bold. A channel filter corresponds to one or more YouTube channels. In the context of the US election, you can choose videos from the McCain channel, the Obama channel or from all YouTube political channels. For each result, a thumbnail of the video, its title, the time since it was published, the duration and the number of times the query terms are mentioned (i.e. spoken) in the video is provided. By clicking on a result, the video will be displayed in the right column. If you need to see more results, you can navigate between result pages using the links at the bottom of the left column (previous, next, etc.), just like on most Google Search products.

Watching a video

Once you have selected a video, it will appear on the right side of the screen, in the embedded YouTube player, with the list of mentions.
Google Audio Indexing enhances the YouTube player to display mentions of the query terms as yellow markers on the player timeline. For space reasons, we cannot always display all the mentions on the timeline. The top 10 mentions are displayed as a list under the player.
To read the transcript for a given mention, just mouse over the corresponding yellow marker. To listen to the corresponding audio, just click on the marker: the player will automatically jump to the right time in the video. You can also click on the play button located on the left side of the mention.

Searching inside a video

With Google Audio Indexing, you can also restrict your search to the content of a given video. By default, the "Search inside this video" uses the same query term as the video search.
To search for a different term, just type your query in the text form under the video player and press the "Search within this video" button. The mention results are displayed underneath. The yellow markers on the timeline are updated accordingly and you can access the information just like before, using mouse over.



I must say-you have a very nice blog.
Tell me what you think about mine.
