Patent ID: 7571101

Claim:
A system for assigning a numeric score to a sample of a voice pattern of a human subject wherein the score is indicative of the psychological stress level of the human subject comprising: means to convert a verbal utterance of a human subject into electrical signals which are plotted on a Cartesian coordinate system whereby a subject wave pattern having x and y axes are provided; means for filtering said subject wave pattern to remove extraneous values at the leading and trailing edges of said subject wave pattern whereby a working frame is provided for analysis; means to provide a consecutive series of known voice pattern characteristics, wherein said consecutive series exhibits a sequential progression in the degree of blocking in said subject wave pattern; means for assigning a numerical value range to each of the consecutive series of known voice pattern characteristics based on the degree of blocking in said subject wave pattern; means for analyzing said subject wave pattern within said working frame to provide quantified data which define a set of characteristics for said subject wave pattern; means for providing quantified data which define a set of characteristics for said consecutive series of known voice pattern characteristics; means for comparing said quantified data of said subject wave pattern within said working frame to said quantified data for each of said known voice pattern characteristics to ascertain a match between said subject wave pattern and one or more of said known voice pattern characteristics; and means for generating a score for said subject wave pattern based on said one or more matching known voice pattern characteristics.
