“OK Google” has been a stable for Google Search for as long as I can remember. OK that's not true, it's fairly new, but since its birth, speaking your search queries has been a wonderful convenience. While mobile has had it for a bit, Google has been experimenting with adding this feature to its desktop counterparts in both the browser and ChromeOS variants. Those wanting to use this feature though would have to either install an extension from the Web Store or get in on Chrome test builds — something that could create a headache by exposing people to buggy test features. Well, as of today, that's no longer an issue as Google has released the feature into the latest stable build of the Chrome web browser and ChromeOS.
Those wanting to search via their voice, schedule a reminder, or set a timer and meet the language/geographical requirements for the new feature can head to Chrome and check for the update. Enjoy!
