Amazon has tweaked the settings for its Alexa voice AI to allow users to opt out of their voice recordings being manually reviewed by the company’s human workers.

The policy shift took effect Friday, according to Bloomberg, which reports that Alexa users will now find an option in the settings menu of the Alexa smartphone app to disable human review of their clips.
