Apple and Amazon announced Friday they would curtail the use of humans to review conversations on their digital voice assistants, a move that gives users more privacy controls over their communications.
Apple said it would stop using contractors to listen in on users through Siri to grade the voice assistant's accuracy after an Apple whistleblower had told the Guardian that the contractors responsible for "grading" the accuracy of the digital assistant regularly overheard conversations about doctors' appointments, drug deals and even couples having sex. Their job was to determine what triggered Siri into action - whether the user had actually said, "Hey, Siri" or if it was something else, such as the sound of a zipper.
Apple said it would suspend the global analysis of those voice recordings while it reviewed the grading system. Users will be able to opt out of reviews during a future software update.
"We are committed to delivering a great Siri experience while protecting user privacy," said Cat Franklin, an Apple spokeswoman, in an email to The Washington Post.
Later Friday, Amazon updated its privacy policy regarding voice recording made by its Alexa service. Amazon will now let users opt out of having humans review those recordings, selecting a new option in the settings of the Alexa smartphone app. Amazon employees listen to those recordings to help improve its speech-recognition technology.
