If you use Skype’s AI-powered real-time translator, brief recordings of your calls may be passed to human contractors, who are expected to listen in and correct the software’s translations to improve it.
That means 10-second or so snippets of your sweet nothings, mundane details of life, personal information, family arguments, and other stuff discussed on Skype sessions via the translation feature may be eavesdropped on by strangers, who check the translations for accuracy and feed back any changes into the machine-learning system to retrain it.
An acknowledgement that this happens is buried in an FAQ for the translation service, which states:
Microsoft reckons it is being transparent in the way it processes recordings of people’s Skype conversations. Yet one thing is missing from that above passage: humans. The calls are analyzed by humans. The more technological among you will have assumed living, breathing people are involved at some point in fine-tuning the code and may therefore have to listen to some call samples. However, not everyone will realize strangers are, so to speak, sticking a cup against the wall of rooms to get an idea of what’s said inside, and so it bears reiterating.
Especially seeing as sample recordings of people’s private Skype calls were leaked to Vice, demonstrating that the Windows giant’s security isn’t all that. “The fact that I can even share some of this with you shows how lax things are in terms of protecting user data,” one of the translation service’s contractors told the digital media monolith.

The translation contractors use a secure and confidential website provided by Microsoft to access samples awaiting playback and analysis, which are, apparently, scrubbed of any information that could identify those recorded and the devices used. For each recording, the human translators are asked to pick from a list of AI-suggested translations that potentially apply to what was overheard, or they can override the list and type in their own.
Also, the same goes for Cortana, Microsoft’s voice-controlled assistant: the human contractors are expected to listen to people’s commands to appraise the code’s ability to understand what was said. The Cortana privacy policy states:
Buried deeper in Microsoft’s all-encompassing fine print is this nugget (with our emphasis):
