Google adds speech recognition to video search
You can check out the new feature by adding the Google Election Video Search Gadget to your iGoogle page. Or you can view the gadget as a standalone page. Just enter a search term and Google will locate videos where the word is uttered. Google will also add little yellow markers to the timeline letting you know where the word occurs.
Google uses speech recognition technology to automatically transcribe the text of these videos and add them to an index. Videos uploaded by politicians to their official YouTube channels are indexed within a few hours.
Google certainly isn't the first site to combine speech recognition with video search. Blinkx and EveryZing offer similar services. But Google is the 800 pound gorilla in both the search and online video worlds.
