If your search query match some YouTube video, the positions are indicated by yellow markers – hover the mouse to read the transcribed text as in the screenshot.

Like Blinkx search, Google uses their own speech recognition technologies to listen to the audio portion of the video and then transcribe speech into text.

And this happens real fast – Google can search and transcribe text from new videos with hours after they get uploaded on YouTube.

Imagine how useful Google search will become when it expands their video speech recognition to other video content like TV clips, news videos, video podcasts, etc.
