Google Voice Search or Search by Voice is a Google product that allows users to use Google Search by speaking on a mobile phone or computer, i.e. have the device search for data upon entering information on what to search into the device by speaking.

Initially named as Voice Action which allowed one to give speech commands to an Android phone. Once only available for the U.S. English locale – commands were later recognizable and replied to in American, British, and Indian English; Filipino, French, Italian, German, and Spanish.^[1]

In Android 4.1+ (Jelly Bean), it was merged with Google Now.

In August 2014, a new feature was added to Google Voice Search, allowing users to choose up to five languages and the app will automatically understand the spoken language.^[2]

On June 14, 2011, Google announced at its Inside Google Search event that it would start to roll out Voice Search on Google.com during the coming days.^[3][4]

Google rolled out the support, but only for the Google Chrome browser.

Google Voice Search was a tool from Google Labs that allowed someone to use their phone to make a Google query. After the user called (650) 623-6706, the number of Google Voice's search system, they would wait for the words Say your Search Keywords and then say the keywords. Next, they would either wait to have the page updated, or click on a link to bring up the search page the user requested. At the moment, both the demo of this service and the page have been shut down. Since the introduction of the service, products from Google, such as GOOG-411, Google Maps and Google Mobile App, have been developed to use speech recognition technology in various ways.

On October 30, 2012, Google released a new Google Search app for iOS, which featured an enhanced Google Voice Search function, similar to that of the Voice Search function found in Google's Android Jelly Bean and aimed to compete with Apple's own Siri voice assistant.^[5] The new app has been compared favorably by reviewers to Siri and The Unofficial Apple Weblog's side-by-side comparison said that Google's Voice Search on iOS is "amazingly quick and relevant, and has more depth [than Siri]".^[6] Of note is that as of May 2016 20% of search queries on mobile devices were done through voice with the number expected to grow.^[7]
