Collection Overview
In Forensic Phonetics, the two most relevant acoustic-related analyses are: (1) analyzing the similarity between voices recorded in different contexts (questioned and reference samples) and (2) analyzing the typicality of these voices within the sociolinguistic community of the individuals under criminal investigation. Both analyses require robust acoustic parameters that demonstrate significant voice similarities only when the samples come from the same individual. Additionally, for a successful Speaker Comparison task, the acoustic parameter values should be atypical, making them distinguishable from those of other individuals within the same linguistic community. This necessitates research on acoustic measures with low intra-speaker variability and high inter-speaker variability, which justifies this Methods Collection proposal. The study of novel measures derived from both segmental and prosodic domains, particularly those that address robustness across different speaking styles, languages, attitudes, and emotions, will be highly appreciated. Furthermore, research on the connection between perceptual protocols (e.g., Laver's VPA) and acoustic analysis is also encouraged.
