How NSA Software Has Been Transcribing Phone Calls for the Past Decade
Just when you thought NSA spying couldn’t possibly get any more invasive, the Intercept’s Glenn Greenwald revealed shocking information about the NSA’s ability to “convert spoken words into searchable text” on Tuesday. The new piece is based on the files the journalist received from whistle-blower Edward Snowden and includes details about what analysts call “Google for voice,” software which allows the government agency to do keyword searches through any phone calls they’ve recorded.
Alarmingly, as Greenwald points out, while we don’t know the extent to which this software has been used domestically, the USA Freedom Act doesn’t even begin to address it.
The Intercept:
Though perfect transcription of natural conversation apparently remains the Intelligence Community’s “holy grail,” the Snowden documents describe extensive use of keyword searching as well as computer programs designed to analyze and “extract” the content of voice conversations, and even use sophisticated algorithms to flag conversations of interest.
The documents include vivid examples of the use of speech recognition in war zones like Iraq and Afghanistan, as well as in Latin America. But they leave unclear exactly how widely the spy agency uses this ability, particularly in programs that pick up considerable amounts of conversations that include people who live in or are citizens of the United States.
Spying on international telephone calls has always been a staple of NSA surveillance, but the requirement that an actual person do the listening meant it was effectively limited to a tiny percentage of the total traffic. By leveraging advances in automated speech recognition, the NSA has entered the era of bulk listening.
And this has happened with no apparent public oversight, hearings or legislative action. Congress hasn’t shown signs of even knowing that it’s going on…
Voice communications can be collected by the NSA whether they are being sent by regular phone lines, over cellular networks, or through voice-over-internet services. Previously released documents from the Snowden archive describe enormous efforts by the NSA during the last decade to get access to voice-over-internet content like Skype calls, for instance. And other documents in the archive chronicle the agency’s adjustment to the fact that an increasingly large percentage of conversations, even those that start as landline or mobile calls, end up as digitized packets flying through the same fiber-optic cables that the NSA taps so effectively for other data and voice communications.
The Snowden archive, as searched and analyzed by The Intercept, documents extensive use of speech-to-text by the NSA to search through international voice intercepts — particularly in Iraq and Afghanistan, as well as Mexico and Latin America.
For example, speech-to-text was a key but previously unheralded element of the sophisticated analytical program known as the Real Time Regional Gateway (RTRG), which started in 2005 when newly appointed NSA chief Keith B. Alexander, according to the Washington Post, “wanted everything: Every Iraqi text message, phone call and e-mail that could be vacuumed up by the agency’s powerful computers.”
