Google has recently launched Google Audio Indexing for video. It appears they are using their new speech recognition technology to index the words spoken in YouTube's political channel videos. With this technology users can type in a search term and navigate directly to the part of videos where the term was used.

Google calls this GAudi and eventually this will probably become a powerful YouTube search technology and add a whole new dimension to SEO (Search Engine Optimization). Imagine the day when users will see the YouTube videos ranked by the keywords spoken within the videos. If you haven't started creating and distributing video content you should definitely considered it for the near future.
