犯罪嫌疑人证词的真伪辨别主要有三种方法来检测,即非言语特征、测谎、言语特征。目前在言语特征方面研究比较成熟的技术主要有陈述有效性评估(SVA)技术和真实监控(RM)技术两种,许多学者也对其进行了实证研究。通过系统总结前人研究的成果,发现其在理论基础、标准的数量以及权重上存在争议。 There are three main methods to detect the authenticity of the suspect’s testimony: non-verbal features, polygraph, speech features. At present, there are two kinds of technologies that are mature in the study of speech features, that is, presentation validity evaluation (SVA) technique and real monitoring (RM) technique, and many scholars have conducted empirical research on it. By systematically summarizing the results of previous studies, we find that there are controversies on the basis of theory, quantity and weight of standards.
