TOP SECRET Detail the nature of the Experiment as a high level plain English description. Refrain from using overly technical terms if possible. Justify briefly why this Experiment should run, with a high level summary of Experiment, Conditions, De-risking effort, Business Case and Expected Outcomes/ Benefits. As part of the Joint Capability Activity (JCA) in partnership with GCHQ, experiments by Voice Analytics are to be conducted within the Joint Collaboration Environment (JCE) using DISTILLERY. VoiceRT is NSA’s currently deployed voice analytics technology that delivers integrated speaker ID (SID), language ID (LID), gender ID (GID), dual-tone multi-frequency (DTMF) detection, speech activity detection (SAD), and phonetic keyword search (i.e., direct keyword search on audio data) in more than 25 key foreign languages. VoiceRT requires specific hardware, proprietary process provisioning software (Tibco), and uses an older voice analytics technology. A new initiative is underway to create the next generation of VoiceRT that operates on commodity hardware (GHOSTMACHINE), replaces the Tibco process provisioning software with DISTILLERY, and makes use of the latest voice analytics technology from R64 (including the new Speech-to-Text). Voice Analytics experiments will occur in phases with this proposal being the first phase. The business case for running Phase 1 of the Voice Analytics experiment in the JCE is to demonstrate the following: • LPT voice data can be ingested into GHOSTMACHINE and passed to DISTILLERY for processing at the rate of arrival. • DISTILLERY can run a subset of voice analytics (SAD, GID, and LID) on voice data. • Running multiple analytics on voice data in parallel produces the same result as running each analytic independently. • DISTILLERY can pass results from an analytic as input to a follow-on analytic with decision points throughout the dataflow based on analytic results (e.g. If GID reports the speaker is male, pass the data to LID; otherwise, stop processing the voice cut). • DISTILLERY is capable of resource management at high speeds. If a voice analytic process in DISTILLERY is unable to handle the ingest rate, DISTILLERY can spawn additional voice analytic processes. Similarly, if resources from one set of voice analytic processes can be better used elsewhere, DISTILLERY will remove from memory some/all of the set of voice analytic processes. • Determine the scalability as additional analytics are loaded into memory and processing data. How is the previous bullet affected as free memory goes to zero? How quickly can voice analytic processes be spawned and broken down?

TOP SECRET Benefits Outcome Expected Benefit How will benefit be measured? Demonstrate the JCE environment (including GHOSTMACHINE and DISTILLERY) can get data to core analytics at ingest rate. The JCE environment can be used to process voice content. GHOSTMACHINE and DISTILLERY can maintain speeds required to processes voice on a 10G link. Add DISTILLERY to GHOSTMACHINE stack. Monitor ingest pick-up directory that feeds DISTILLERY input. Demonstrate the JCE architecture can affordably scale in line with other VoIP accesses. If the outcome is true, then the JCE environment provides a good test environment for future voice processing experiments. If VoiceRT is to eventually be replaced with this new technology, then tests must be run against a similar environment. This experiment also tests DISTILLERY’s ability to dynamically manage resources, which is a requirement for our voice processing. Compare quantity of VoIP data processed at JCE against that collected on similar links at NSAW and GCHQ. Demonstrate voice analytic processing of incoming data significantly reduces the amount of unintended collection reaching long-term stores by filtering on Language ID, Speech Activity Detection, and Gender ID. Analysts can be directed to smaller, more probable collected voice cuts. Since voice files can be very large, significantly reduces the amount of longterm storage required. DISTILLERY will be configured to separate wanted and unwanted VoIP files in separate storage locations. Comparing sizes of the two locations will provide an approximation for the ratio of wanted versus unwanted traffic.

TOP SECRET Demonstrate voice processing can be performed on commodity hardware (GHOSTMACHINE). Current voice processing at NSA has hardware specific requirements. Voice analytics can be executed on commodity hardware alongside other applications. Allows for easier hardware maintenance and shorter deployments. Analysts will confirm resulting data has been filtered without a loss of wanted traffic. JCE experiments can process content while remaining in compliance with US and UK laws. Future experiments requiring content for processing can leverage. If MONKEYPUZZL E can safely produced selected content to the experiment, then it should be in compliance.

TOP SECRET Plan I Timeline, including dependencies/pre-requisites, set-up, operation, evaluation, reporting, closedown. Also includes deliberate outages of equipment. As stated in the business case , this is Phase 1 of the Voice Ana lytics Experiment. This phase is div ided into four sub-exper iments focusing on dataflow through a select group of voice analytics (SAD, GID, LID) in DISTILLERY. All four experimen ts require access to CSDF vo ice files. Future phases will cons ider SOTF once GHOSTMACH INE can support th is format. Exp. 1: Independent Analytic Tests (-1 week) - Designed to test the dataflow from DISTILLERY input , through a few process ing blocks , and the output displayed to a GUI.

TOP SECRET Exp. 4: Dynamic Resource Manager Tests (-2 week)- Builds off of the third exper iment. The SAD algorithm is much faster than GID and LID. In this exper iment, DISTILLERY should be able to dynam ically create/remove additional GID and LID analyt ic processes to compensate for GID and LID processes falling behind or becom ing idle. A more advanced part of this experiment wo uld be to monitor DISTILL ERY's response to all system memory in use; for example, 100 GID analyt ics and 150 GID analyt ics are still falling behind, but no system memory exists to spawn additional processes. Does one set of analytic processes starve or do we see a constant exchange of memory between GID and LID?
