The CVSA software provides graphical representations of stress, but trained operators are necessary to correctly interpret the data and differentiate between stress caused by deception and other factors.
An operator's bias or assumptions about a subject can influence how they interpret stress patterns, potentially leading to inaccurate conclusions.
Regular calibration ensures that the equipment and software function accurately, reducing the likelihood of misinterpretation due to faulty or inconsistent data.
Proper training and experience allow operators to better understand and interpret the nuances of vocal stress patterns, reducing errors and improving reliability.
Remaining neutral minimizes the risk of introducing stress in the subject due to the operator’s behavior, ensuring that the results are more likely to reflect genuine stress responses rather than environmental or psychological influences.
