Speech deception and voice "hijacking" techniques are now sophisticated beyond the ability of any single detection methodology. Deceptive speech detection requires an array of analysis tools to collectively provide an acceptable probability of detection. An effective Voice Authentication Monitoring System is envisioned as a "work bench" tool set to detect, analyze and assess speech deception. Development of a single methodology which exploits articulatory trajectories of individual speakers in analyzing continuous, "unwitting" speech has potential of superior performance involving voice authentication, speech verification and recognition.

Benefits: The proposed research will yield a new tool methodology that will facilitate the development of a Voice Authentication Monitoring System. The technique of speech featuring a trajectory mapping is applicable to law enforcement, drug intradiction and counter terrorist efforts.
