OK Google in Desktop Chrome

Google Voice Search works in Chrome for desktop, not only in Android and iOS. Just click the microphone icon from the search box and you can tell Google what do you want to know, assuming that you have a microphone.

Now you can bypass the microphone icon and use the hotword "OK Google" when you're using Google search or the new tab page. You need to install this extension first.


"Chrome will listen for you to say 'Ok Google' and then send the sound of the next thing you say, plus a few seconds before, to Google," informs the options page. By default, Google stops listening after 5 minutes to reduce battery consumption on a laptop.

For example, if you tell Google "show me some Brad Pitt movies", Google will show results for [Brad Pitt movies].
