Cisco Pulse gets a pulse on the 2012 GOP debates: the power of voice recognition for video search

We collectively watch over 3 billion hours of video a month on YouTube alone.  And it’s not just crazy kitty antics or babbling babies:  among my video-related tasks this week, I learned how to change a faucet, caught up on some interesting TED talks, and reviewed the latest product meeting for an upcoming release.

Each of these required searching for videos, which for most of us means hunting and pecking. At best, we sort video by tags that someone has manually selected, and then drag the video scroll bar back and forth until we find the information we need.  Can you say, “time consuming”?

Another thing that some regard as time consuming, yet a civic duty, is listening to political debates.  Over the past nine months, the GOP candidates met head to head in over 20 debates to discuss a wide range of topics. But for viewers who weren’t able to tune in for each 90-minute debate …  imagine being able to instantly find every clip of former Massachusetts Governor Mitt Romney talking about “immigration,” or to automatically parse each debate and identify who spoke about the “Supreme Court,” the “constitution,” or the “auto industry.”

With Cisco Pulse, Cisco’s video analytics solution, we used voice recognition to analyze each of the last four Republican debates. From January 19th through February 22nd, these debates featured the Republican candidates at the time: Romney, former Pennsylvania Senator Rick Santorum, former House Speaker Newt Gingrich and Texas Representative Ron Paul.

This is more than just speech-to-text technology. Using a Cisco voice recognition engine, Pulse is able to sort each video by top keywords and speakers. That means you can jump instantly to the specific segment of video you need, or browse entire libraries of video by content or speaker, instead of just manually entered tags. You can instantly see the top keywords for each video … who said what in context. The infographic below provides a snapshot of the findings from Cisco Pulse – a summary of topics from each debate and who said what.
