Microsoft has revealed that humans could be listening to "short snippets" of voice conversations on its audio services like Skype and virtual assistant Cortana, Motherboard reported Wednesday. Microsoft confirmed the report saying the disclosure came in an update to its privacy statement.
"We realized, based on questions raised recently, that we could do a better job specifying that humans sometimes review this content," a Microsoft spokesperson said in an emailed statement. "We've updated our privacy statement and product FAQs to add greater clarity and will continue to examine further opportunities to improve."
Microsoft's privacy statement says human review is used to help build, train and improve the accuracy of its artificial intelligence systems.
The spokesperson said Microsoft always works to "de-identify the content provided to vendors," as well as requiring them to sign non-disclosure agreements.
"[We] require that handling of this data be held to the highest privacy standards set out in European law," the Microsoft spokesperson added.
Motherboard added Wednesday afternoon that Microsoft's human review contractors are paid between $12 and $14 an hour for the job, and transcribe up to 200 audio clips every hour. This could include hearing "personal and sensitive information" via Cortana recordings, Motherboard reported.
