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 says that the recordings are identified by numbers rather than user names, but 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,” reports The Next Web.
What does Google have to say about all this? That they only transcribe and use “about 0.2% of all audio clips” to improve their voice recognition technology.
