Chrome web browser users have been able to carry out Google searches using voice commands for a while by enabling the Voice Search Hotword extension—now, that extension becomes moot as all Google web users will have the option by default.
Google’s voice search becomes apparent as a microphone icon appears on the far right side of the search box, with words next to it: Say “Ok Google.” When a user complies, Google responds by erasing the screen and then displays a large red microphone icon along with the words “Speak Now.” When words are spoken, they (or a close facsimile thereof) appear on the screen. When Google senses the user has finished their search request (by remaining silent for a moment) the spoken words are entered into the search box and the Enter command is executed, generating a page of query results.
Allowing users to use their voice instead of their fingers on a keyboard extends Google’s search capabilities, bringing Apple Siri-like functionality to computers and very soon to mobile devices (for now the voice application will only work with the browser—Chrome OS will be updated at a later time.) The voice feature also allows for setting reminders in Google Now and for getting directions.
