Past research suggests differences in speech patterns within a language stem from sociolinguistic factors. Differences in casual speech patterns provide a framework for differences in deceptive speech patterns, which in turn are used in forensic linguistic analysis. A paucity of research concerning sociological and psychological differences in deceptive speech has resulted in uncertainty; in practice, suspects are linguistically fingerprinted without substantial supporting evidence. As a contribution to forensic linguistics, this study examines phrasing with proven differences between casual and deceptive speech to compare different sociolinguistic groups in the United States. Data was collected from police interrogations of later-convicted felonious criminals and were grouped based on regional dialect, racial dialect, gender, and the classification of their crime. The authenticity of the data better contributes to deception research than simulated deception, serving to find possible solutions to current inaccuracies in deception detection technology. |
