Forensic Deception Detection Using Layered Voice Analysis: A Case Study on the Sharon Raj Murder Investigation

Abstract

This study analyzed deception and stress markers in the Sharon Raj murder case using layered voice analysis (LVA) 6.50. The research examined publicly available phone recordings of the accused, XYZ, to identify emotional instability, cognitive suppression, and inconsistencies in her statements. Key findings revealed high stress and deception markers when discussing the poison, medicine, and relationship details. Multiple segments showed medium to high risk, indicating possible withheld information or manipulative responses. The study highlights the importance of forensic voice analysis in criminal investigations by how LVA can assist in detecting deception. However, findings should be corroborated with physical evidence and behavioral analysis for legal accuracy.
