Abstract

Voice quality derived from long-term laryngeal settings stands out as a potentially individualizing trait of speakers. This places it in an advantageous situation with respect to other phonetic parameters used in forensic linguistics. However, anyone confronted with its analysis will immediately run into a methodological difficulty stemming from its inherently multidimensional nature. In this lies its main disadvantage and the fundamental reason why its analysis is not always considered in the traditional approach used in the comparison of speakers for identification purposes. Based on an experimental inquiry on voice disguised by means of falsetto, this study shows that it is possible to work with a reduced set of laryngeal features responsible for voice quality and facilitate its interpretation and explanation, which is a critical issue for forensic practice.

论音质在司法语音学中的适用性
源自长期喉部环境的音质是扬声器潜在的个性化特征。相对于法医语言学中使用的其他语音参数,这使其处于有利的地位。然而,任何面对其分析的人都会立即遇到方法上的困难,这源于其固有的多维性。这就是它的主要缺点,也是为什么在为识别目的对说话者进行比较的传统方法中,它的分析并不总是被考虑在内的根本原因。基于对假声伪装声音的实验研究,本研究表明,有可能处理一组负责声音质量的喉特征,并促进其解释和解释,这是法医实践中的一个关键问题。
