Computer voice stress analysis

Its validity, clearly contribute to the involuntariness of the suspects' confessions. One suspect went so far as to say, "Even though I don't remember killing (the victim) your test shows that I did so I must have." The following is a summary of some of the studies that have been conducted on the CVSA:An analysis of Voice Responses for the Detection of Deception, 1994. Victor L. Cestaro and Andre B. Dollins Results: "Results of the analyses suggest that no single human voice measures, as collected and analyzed in this study, can reliably discriminate between truthful and deceptive responses."A Comparison between Decision Accuracy Rates Obtained Using the Polygraph Instrumentation and the Computer Voice Stress Analyzer (CVSA) in the Absence of Jeopardy, 1995. Victor L. Cestro Department of Defense Polygraph Institute. Results: "The decision accuracy utilizing the traditional polygraph and its procedures was significantly higher than that of the CVSA approach."A Comparison of Accuracy Rates Between Detection of Deception Examinations Using the Polygraph and the Computer Voice Stress Analyzer in a Mock Crime Scenario, 1996. Victor Cestaro, Department of Defense Polygraph Institute. Results: "The data analysis indicate that within the test paradigm used in this study, neither the polygraph nor the CVSA test chart evaluators were able to reliably differentiate between truthful responses and deception at levels greater than chance."Effectiveness of Detection of Deception Examinations Using the Computer Voice Stress Analyzer (CVSA), 1998. Michael Janniro and Victor Cestaro. Results: "In summary, although there is evidence to support the basic electrical theory of operation of the CVSA, the instrument failed to function in a manner that would allow examiners to discriminate between truthful and deceptive test subjects." The average accuracy rate of the CVSA in these studies was 38.7%. Permission is hereby granted to those who wish to share or copy this article.

2012): 259–84. Full text Abstract: AbstractSpelling errors in digital documents are often caused by operational and cognitive mistakes, or by the lack of full knowledge about the language of the written documents. Computer-assisted solutions can help to detect and suggest replacements. In this paper, we present a new string distance metric for the Persian language to rank respelling suggestions of a misspelled Persian word by considering the effects of keyboard layout on typographical spelling errors as well as the homomorphic and homophonic aspects of words for orthographical misspellings. We also consider the misspellings caused by disregarded diacritics. Since the proposed string distance metric is custom-designed for the Persian language, we present the spelling aspects of the Persian language such as homomorphs, homophones, and diacritics. We then present our statistical analysis of a set of large Persian corpora to identify the causes and the types of Persian spelling errors. We show that the proposed string distance metric has a higher mean average precision and a higher mean reciprocal rank in ranking respelling candidates of Persian misspellings in comparison with other metrics such as the Hamming, Levenshtein, Damerau–Levenshtein, Wagner–Fischer, and Jaro–Winkler metrics.

"An epidemiological study of computer related health problems and stress among bank employees in the vicinity of a tertiary care hospital." International Journal Of Community Medicine And Public Health 7, no. 10 (September 25, 2020): 3941. Full text Abstract: Background: Due to the upsurge in information technology and daily increase in the number of computer usage in banking sector and increasing use of online banking services in India, there is need for research into computer related health problems. The objectives of the study were to estimate prevalence of computer related health problems and stress among Bank employees and to study its association with their working environmental conditions.Methods: A cross sectional study was conducted, with a pre-tested, pre-designed questionnaire in 19 banks among 255 bank employees aged 25 to 50 years by census enumeration method in urban field practice area for 18 months. Inclusion criteria included employees working in current job since the past 2 years and on computer for at least 5 days/week and minimum 4 hours/day. The questionnaire included socio-demographic details, working environment and problems experienced while working on computers. Modified standardized Nordic questionnaire (musculoskeletal), depression anxiety stress scales (DASS) (stress), Snellen`s-Jaeger’s chart (visual acuity) and digital lux meter (illumination) was used. Statistical analysis was done using Statistical Package for the Social Sciences (SPSS) version 25.0.Results: The proportion of musculoskeletal, symptoms of Carpal tunnel syndrome due to keyboard use, visual problems and stress was found to be 69%, 60%, 58% and 38% respectively.
