Abstract

The idea of detecting deception from speech is very attractive from a law enforcement perspective, yet research considering the possibility has yielded conflicting results, due to the practical difficulties in investigating the topic. Scientific research is yet to provide forensic linguistics with a reliable means of discerning lies from truths. The present study explores the relationship between truthfulness and pausing behaviour. Various aspects of the acoustics of pausing behaviour were investigated for Standard Southern British English in 30 mock police interviews from the DyViS database (Nolan et al. 2009). A novel distinction was made between prescribed and unprescribed lies, to delineate a potential source of differences in the unscripted content of speakers’ untruthful responses. Among pause duration measures, statistically significant differences were found across all three response types (truth, prescribed lie, unprescribed lie) for response latency, between truths and lies for initial filled pauses, and between unprescribed lies and the other response types for silent pauses. For pause frequency measures, only internal filled pauses showed a statistically significant difference: truths differed from both types of lies, but prescribed lies did not differ from unprescribed lies. Theories of cognitive effort and attempted control are drawn on in accounting for these findings.

暂停和“奥赛罗错误”

从执法的角度来看，从言语中检测欺骗的想法非常有吸引力，但由于调查该主题的实际困难，考虑到这种可能性的研究产生了相互矛盾的结果。科学研究还没有为司法语言学提供一种可靠的方法来辨别真假。本研究探讨了真实性与停顿行为之间的关系。在DyViS数据库的30个模拟警察访谈中，对标准英国南部英语中暂停行为的声学各个方面进行了调查(Nolan et al. 2009)。研究人员对规定的谎言和非规定的谎言进行了新颖的区分，以描述说话者不诚实回答中非规定内容差异的潜在来源。在暂停时间测量中，在所有三种反应类型(真相、规定的谎言、非规定的谎言)中，在反应延迟中，在真实和谎言之间，在初始填充停顿中，在非规定的谎言和其他反应类型之间，在沉默停顿中，都发现了统计学上显著的差异。对于暂停频率的测量，只有内部填充的停顿显示出统计学上的显著差异:事实与两种类型的谎言不同，但规定的谎言与非规定的谎言没有区别。认知努力理论和尝试控制理论被用来解释这些发现。
