Google contractors are secretly listening to your Assistant and Home recordings

Not only is your Google Home device listening to you, a new report suggests there might be a Google contractor who’s listening as well. Even if you didn’t ask your device any questions, it’s still sending what you say to the company, who allow an actual person to collect data from it.


VRT, with the help of a whistleblower, was able to listen to some of these clips and subsequently heard enough to discern the addresses of several Dutch and Belgian people using Google Home — in spite of the fact some hadn’t even uttered the words “Hey Google,” which are supposed to be the device’s listening trigger.

The person who leaked the recordings was working as a subcontractor to Google, transcribing the audio files for subsequent use in improving its speech recognition. They got in touch with VRT after reading about Amazon Alexa keeping recordings indefinitely.

According to the whistleblower, the recordings presented to them are meant to be carefully annotated, with notes included about the speakers presumed identity and age. From the sound of the report, these transcribers have heard just about everything. Personal information? Bedroom activities? Domestic violence? Yes, yes, and yes.

While VRT only listened to recordings from Dutch and Belgian users, the platform the whistleblower showed them had recordings from all over the world – which means there are probably thousands of other contractors listening to Assistant recordings.

The VRT report states that the Google Home Terms of Service don’t mention that recordings might be listened to by other humans.

The report did say the company tries to anonymize the recordings before sending them to contractors, identifying them by numbers rather than user names. But again, VRT was able to pick up enough data from the recordings to find the addresses of the users in question, and even confront some of the users in the recordings – to their great dismay.

Google’s defense to VRT was that the company only transcribes and uses “about 0.2% of all audio clips,” to improve their voice recognition technology.
