Google has finally extended handsfree search to Chrome through the Google Voice Search Hotword extension (in Beta) which is available for download through the Chrome Web Store.
It's worth pointing out that the feature is
available in English only in the US. After downloading and installing the extension, users need to visit Google.com and say "Ok Google" followed by their conversational search query or command. Since the search experience is totally handsfree, one just needs to repeat the command again to switch to another search as the extension makes the browser sensitive to the "Ok Google" keyword. You can even set a reminder and make it show on Google Now through the tool, provided you're signed-in with the same Google account.
Google had first showcased conversational search at the Google I/O event in May. It had
rolled out the feature on Chrome browser for Mac, Windows and Linux with the updated version (version 27) of the browser, later that month.
Similar to voice search and Google Now apps on Android and iOS devices, the new functionality allowed users to ask Google questions by speaking with the search engine in a conversational manner using words and phrases, eliminating the need to key in search terms manually. The search engine also responds in a more natural, human-like way to create a feeling of personalisation.
However, Google had not rolled out a totally hands-free experience and it was not possible to switch to the next search just by saying 'Ok Google' at that time.
It's worth pointing out that Google had
first launched voice search on desktop via Chrome in 2011.
