The Intercept has released a new document from Edward Snowden's cache of government files describing how the NSA has been converting voice calls to searchable text documents for nearly a decade. The NSA has long monitored signals intelligence (SIGNIT) around the world (as is its primary function), especially in active combat zones like Afghanistan and Iraq as well as in Latin America. Traditionally, this sort of data gathering required that a live operator listen in on calls and translate them in real-time. However, the NSA has reportedly developed what it calls "Google for Voice"; an automated system that provides a rough but keyword searchable transcription. According to the documents, the NSA has also developed analytical programs and sophisticated algorithms to flag conversations for human review.
