A widely held myth says Google eavesdrops on her life to enhance search results. It doesn"t, yet should it?


Many Google users believe the agency records audio through phones and also computers, then uses those recordings come the AutoComplete options in Google Search.

You are watching: Does google listen to your microphone

I asked pendant on Google+ around this and one wrote: "If me and also my wife room talking about some random subject like exactly how long turtles live, I"ll kind "how" and also it will certainly fill in "long carry out turtles live" favor it to be listening. And also I"m terrified and also impressed."

The anecdotal proof is convincing. Some say AutoComplete is an ext than simply specifically accurate, it"s personal. One commenter stated his friend gained an deal with over the phone from his wife. As soon as he began to type that attend to into Google Maps, the application suggested the specifically correct resolve after that typed just the an initial number of the address.

Another flatly proclaimed: "the mic is always on listening mode."

What"s walk on here?

What Google in reality records

Google is careful around when, where and how it documents user audio. The only method for Google to end up v a record of her conversations is because that you to use among its voice products, such as the Google app, Google Assistant in the Allo message app, Chrome browser, Pixel phone or Google residence appliance. You additionally have to take it deliberate action. You have to press the microphone symbol or say one of two people "OK Google" or "Hey Google."


The AutoComplete function of Google find is periodically so precise that users wonder: Is Google eavesdropping on my conversations?

Google applies voice-recognition software to her words, and also uses those words to procedure your request or command.

Google maintain a copy of the recordings to enhance its software. The firm is do the efforts to be the the opposite of sneaky. It offers a detailed history of every recording it has actually on the user"s "My Activity" web page.

Each record or set of recordings is gift on its own card.

The recordings are detailed by date and also service (for example, "Assistant," "Google App" or "google.com." on the left you deserve to see the message version of her command, i beg your pardon is a connect that, once clicked on, take away you come Google Search outcomes for those words. On the best you"ll uncover a "play" button, for this reason you have the right to listen to each recording. A "more options" menu on the top right of each card permits you come delete any recording.

It"s unlikely for a recording to happen by accident. From a phone, for example, the phone have to be unlocked and also the recording begun by details user action, such as pressing the icon. On a Pixel phone, the user can collection up automatically listening mode by transforming the default in settings to enable the "Trusted Voice" setting. That provides the phone listen for the "OK Google" command.

The Google house product likewise listens because that the "OK Google" command.

So how have the right to the uncanny AutoComplete alternatives reported through some customers be explained?

It"s magic

I think the best explanation is the Google is producing AutoComplete alternatives by means beyond the user"s understanding. Think about four possibilities.

1. Coincidence

Let"s say you do 100 searches utilizing Google Search. Probability would indicate that AutoComplete will certainly be useful some of the time, useless several of the time and also uncannily accurate some the the time. Periodically a specific thing you"re searching for just wake up by simultaneously to be something lots of other world are searching for, and also therefore shows up in AutoComplete. Periodically you believe you"re coming up with a search query the end of the blue, however in fact you"ve been affected by social trends online.

2. Accident

Google insurance claims it doesn"t hear to "utterances" -- chatter unrelated to a certain voice search or command. Yet sometimes that does. Top top my very own "My Activity" page, much more than 10 percent of the recordings don"t fit Google"s criteria because that audio that should be recorded and also retained. In one case, who I recognize who speaks through thickly accented English claims something that sounds precisely like "OK Google," but that"s not what she said. In others, ns don"t hear anything remotely comparable to "OK Google" ~ above the recording. I just hear a snippet that conversation. Still, a brief one- or two-second sentence the otherwise arbitrarily conversation was tape-recorded in each instance, and also the indigenous therein might have to be factored right into a collection of AutoComplete options.

In various other cases, it"s feasible that words talked in the lift or immediately after a legit "OK Google" command might be included.

Here"s an additional scenario. Let"s speak one person has enabled the "Trusted Voice" setting on a Pixel phone. This human being is visiting a friend, who"s obtained a Google residence device. The friend says to the house device: "OK Google, exactly how tall is Taylor Swift?" 2 days later, after forget the result, the friend through the Pixel goes to do a search, varieties in "how tall is" and also AutoComplete offers "Taylor Swift" in the options. Was Google listening? Yes: The various other person"s "OK Google" command likewise triggered and also recorded top top the Pixel phone without the knowledge of the user.

3. Unexpected sources for signals

It"s clean that with Google Maps, Google has AutoComplete options based ~ above not just my activity, but my wife"s. It"s easy, based on activity, for Google to number out who"s intimately connected. Because that example, it need to be clean to Google the my wife and also I, who are both heavy Google Maps users, generally travel with each other to the same general practitioners coordinates and addresses.

It"s additionally easy come forget that you in reality have previously looked for something. If girlfriend don"t remember that fact, AutoComplete choices can be how amazing accurate.

4. Man-made intelligence

The person mind is no generally capable of expertise the cumulative power of personal data come predict outcomes. Google A.I. Is capable of connecting plenty of dots behind the scene to predict results. If you think about it, someone whose search results generally reveal hypochondria and also who species the words "where can I" into a search bar throughout a flu epidemic is most likely to find for: "where can I acquire a flu shot." The user might wonder: "How walk they know what i was thinking?"

On the last point: scientific research fiction writer Arthur C. Clarke stated that "any saturated advanced technology is identical from magic." Magician David Blaine does impressive tricks. One explanation is that he has magic powers. A far much more likely explanation is that it only looks favor magic since his audience doesn"t know exactly how he go the tricks.

Likewise, Google Search periodically -- commonly not, however sometimes -- produces uncanny results. One explanation is the Google is recording every little thing -- generally not, however sometimes -- and also uses those illicit and illegal recordings to enhance AutoComplete. A far an ext likely explanation is the Google users don"t know just how Google produces AutoComplete options, and are therefore occasionally surprised.

Google isn"t listening all the time. However should it?

With rare and also accidental exceptions, Google doesn"t record your conversations there is no your knowledge or permission for the function of enhancing AutoComplete.

The ideal evidence for this is the truth that AutoComplete isn"t constantly accurate or also helpful.

In various other words, the problem with AutoComplete is not that it"s "too good" as well often, but that it"s not an excellent enough often enough.

If Google actually did hear in on your life, AutoComplete would certainly be amazing. No, much better still, it would be unnecessary.

If Google listened to, recorded and also processed every audible voice and also sound within variety of your phone, tablet computer or laptop and also applied the data to boosting both Google search AutoComplete and also Google Assistant results, friend would obtain amazing strength of awareness, knowledge and also foresight.

Maybe Google actually should record everything.

What if privacy was assured? for example, what if Google verifiably processed audio ~ above the phone and did not retain the recordings, however was may be to use every conversation come improve and also personalize data. And also what if there to be an on-off switch, whereby you could set Google come listen always by default, or only when you threw the switch.
