Within the latest beta release for Google Chrome, the search engine giant has added voice recognition capbitlities. The introduction of the feature follows the same style of voice recognition that has been present within Android devices for some time now. The voice recognition feature allows users to speak various commands that Google recognizes, simply by starting off their request by voicing "Ok Google." Some examples of possible voice recognition abilities include searching the Internet, setting a timer, and even setting a reminder for Google Now.
Users of the latest Google Chrome beta can enable this new feature by going to the Google website, clicking on the mic icon within the search box, and selecting the button that reads "Enable Ok Google."
