Apple halts practice of contractors listening in to users on Siri

Tech firm to review virtual assistant 'grading' programme after Guardian revelations

Apple has suspended its practice of having human contractors listen to users' Siri recordings to "grade" them, following a Guardian report revealing the practice.

The company said it would not restart the programme until it had conducted a thorough review of the practice. It has also committed to adding the ability for users to opt out of the quality assurance scheme altogether in a future software update.
