OK Google Show Us What You've Got!

Recently Google launched a new extension that might be very useful for students.  It is called, Google Voice Search Hotword.  This extension, when downloaded, allows you to talk to Google, hands-free, no typing. Once on the Google search page, simply say, "OK Google" and then ask your question.  The extension sends your question to Google only when it hears you begin with the catch phrase: "OK Google".
For some students who are not strong spellers, a Google search is difficult.  Students with poor typing or even vision difficulties might find this is helpful as they do not need to navigate to the tiny microphone icon that appears in the Google Search Bar.  Yikes that is small! For some of us the idea of our computer just laying in wait listening until we command it is creepy but for a student who struggles, this might be a life saver!
