Statement of Problem During a typical RV session, the subject produces a wealth of spoken material, but only some of this material relates to the chosen target. Unfortunately it is difficult to identify the target-related material without a priori knowledge of which times the subject was engaged in accurate RV. The question posed in this study was whether it is possible to use audio analysis techniques to determine when a subject is accurately describing the intended target. B. Possible Solution Careful listening to tapes of sessions with a single subject suggests that some target-related material was uttered in a different tone of voice than other material (e.g., conversation with the monitor), For this subject, accurate remote viewing appears associated with certain changes in speech behavior, including speaking more softly, more slowly, longer pauses, and with a dream-like quality. In general, if a subject were to exhibit a particular set of speech changes whenever target-related material was being produced, the analyst could use these speech changes to separate the related from the unrelated material without knowledge of the target. We explored the relationship between changes in speech behavior and the accuracy of target descriptions in this study. SECRET Approved For Release 2000/08/07 : CIA-RDP96-00788R001300310001-4

Historical Perspective of Audio Analysis Techniques Earlier research has shown that changes in speech behavior can reflect subtle physiological changes such as those resulting from stress or disease, Two studies representing this research will be described to provide a context for the present study of speech changes observed during RV sessions, These studies illustrate different approaches to speech analysis. The first study was designed to examine how speech behavior may be influenced by task-induced stress .* An arithmetic task requiring a verbal response was repeatedly administered to each of ten male subjects. The difficulty of the task was varied from trial to trial: on some occasions the subject was obviously stressed, and on other occasions he was relatively relaxed. Contrasting responses containing the same test phrase were com- pared by means of critical listening and instrumental analysis. Listeners were able to discriminate between the responses representing the stress and control conditions for many subjects, Level measurements showed that three subjects spoke more softly and one subject spoke more loudly under stress. Measurements of fundamental frequency provided similar results: some subjects raised their vocal pitch, others lowered their vocal pitch, and still others exhibited unique pitch contours when the task became stressful. An extensive comparison of spectrograms demonstrated many other stress-related changes in the speech signal. Temporal and spectral irregularities were observed in the acoustic pulses that are generated in the larynx during speech production. Stress also affected the precision with which particular speech sounds were articulated. The second study was concerned with speech changes that are related to cerebrovascular disorders.®>* The purpose of the study was to develop a subjective method of speech analysis that could be used to identify persons who have suffered a minor stroke. Because stroke affects speech 3 SECRET” Approved For Release 2000/08/07 : CIA-RDP96-00788R001300310001-4

Experiments were conducted to determine whether certain speech attributes observed in the spectrograms could be used to discriminate between a population of diagnosed stroke patients and an age-matched population of normal speakers. Linear discriminant scores based on ratings of only six speech attributes correctly classified 89 percent of the stroke patients and 87 percent of the normal speakers. 4 SEEREE Approved For Release 2000/08/07 : CIA-RDP96-00788R001300310001-4
