  13-7. Biometric devices such as voice stress analyzer and polygraph support
  the determination of the truthfulness of a source. The polygraph is of
  limited usefulness in general HUMINT collection due to the level of
  expertise needed to operate it and the lack of general availability of the
  device to the field. As devices are developed that can remotely collect and
  report information to the HUMINT collector on subtle changes in the
  source’s respiration, heartbeat, perspiration, and eye movement that can be
  indicators of deceit, they can be used to support HUMINT collection.
  MACHINE TRANSLATION AND INTERPRETATION
  13-8. Understanding oral and written communication in a foreign language
  is often the center of effective HUMINT collection operations. The optimal
  solution is to have an individual who is a trained collector of native
  proficiency, totally versed in the local situation and US requirements, with
  the requisite security clearance, who is capable of reporting accurately in
  English. Commanders’ access to such individuals is usually problematic.
  This requirement is met through a combination of MI linguists, contractors,
  native speakers within the DOD system, and locally hired civilian
  translators. Difficulties arise if the proficiency levels of MI linguists are not
  up to mission requirements, or if the linguists do not possess the proper
  language for the theater of operation. Using locally hired translators raises
  security problems. In light of these conditions, an increasingly viable
  solution for the commander is the use of machine translation devices to
  meet some of these requirements.
  13-9. Voice and text translation machines or software are critical in
  augmenting available linguists. This includes natural language processing,
  artificial intelligence, and optical character recognition (OCR) capabilities.
  The basic application of machine translation, such as speech recognition
  and OCRs, dramatically increases the speed of processing information.
  Software programs are becoming widely available that allow a non-linguist
  to determine the intelligence significance of a foreign document, aid
  linguists with laborious tasks, and add consistency to human translation.
  13-10. Machine interpretation is the use of a machine to interpret the
  spoken word between the HUMINT collectors and another individual
  speaking a foreign language. Linguists are in high demand during
  operations and usually limited in number. As machine interpretation
  devices that address this problem become available to the field, they will
  improve the communication ability of non-linguists.
  ANALYTICAL AUTOMATION REQUIREMENTS
  13-11. The requirement for a robust HUMINT single-discipline analytical
  capability extends through all echelons from national level to the OMTs.
  Communication between HUMINT analysts at the operational level and
  analysts at the staff level may best be accomplished through a web-based
  communication capability. Web-based visual analytical tools allow maxi-
  mum analyst participation in the development of products geared to
  mission planning, targeting, and information analysis at all echelons.
