Nexidia, the Atlanta-based company which provides video search software, has an agreement with msnbc.com to crawl, "listen" and create text metadata around msnbc.com video clips. The first implementation is on the msnbc.com Inauguration Player page. The page provides a great deal of multimedia clips going back to FDR. I've pasted a screen shot here.
The quest for metadata in the form of speech-to-text is a bit of the Holy Grail for publishers. EveryZing has been making progress in providing solutions, as we have reported. Adobe will soon be embedding text transcriptions into edit workflow. Nexidia curently has an implementation with Avid, the professional video video editing system. We have also reported on plans at YouTube to provide more rich metadata through speech to text.
