The Computers are Listening: How the NSA Converts Spoken Words Into Searchable Text

Most people realize that emails and other digital communications they once considered private can now become part of their permanent record.

The documents show NSA analysts celebrating the development of what they called “Google for Voice” nearly a decade ago.
