Android users have been enjoying the hands-free voice search of Google Now but desktop Chrome users only have a simple voice search. The new update to Chrome stable puts desktop users on par with its mobile counterpart.
To activate this, open your Chrome’s settings menu, scroll down then click ‘Show Advanced Settings…’. Scroll to the Privacy section, and check the box next to ‘Enable “Ok Google” to start a voice search’ and you’re done. All updated users of Chrome desktop on Windows, Mac, Linux, Chromes OS should see this option.
The catch here is that you must be on a Google startpage or a new tab. It’s still a working progress, we might see improvements and more options soon. It is currently available on English language only. Upcoming updates should bring additional language packs.
