Google Tightens Its Voice Assistant Rules Amid Privacy Backlash

#artificialintelligence 

After months of revelations that smart speakers get a very human intelligence boost from contractors who transcribe and review customer audio snippets, the mea culpas are flowing in. At the end of August, Apple issued a rare apology about how it had handled human review of audio for Siri. Amazon and Microsoft have made it easier for users to understand how their data might be used and control whether or not it is eligible for review at all. And now Google is joining the fray with a set of privacy announcements about Google Assistant. Google paused human audio review worldwide in July after reports that a contractor was leaking audio snippets in Dutch.
