What are speech data? The question is not as trivial as it may seem: every day both theoretical and applied linguistic research come up against problems deriving from bad data management. This topic is particularly thorny in interdisciplinary approaches such as the speech forensics analysis, whereby the recorded speech can be exploited as legal clues, with important repercussions on public security and citizens’ rights. The datum does not exist in nature, being it a consequence of the human analysis of a given phenomenon. In fact, data extraction is based on explicit and implicit theories implemented by the researcher within the application of specific frameworks. Researchers and professionals working on empiric data should be more aware of these underlined processes in order to avoid data misuse and, indeed, maximize results. In this paper, we will briefly address the issue of the speech data epistemology with a particular focus on the interdisciplinary approach required in forensics (e.g. between linguistics and engineering), by discussing examples from Italian real cases. Moreover, it must be clarified what different experts (e.g., lawyers vs. linguists) mean as datum in forensic research.

Abstract
What are speech data? The question is not as trivial as it may seem: every day both theoretical and applied linguistic research come up against problems deriving from bad data management. This topic is particularly thorny in interdisciplinary approaches such as the speech forensics analysis, whereby the recorded speech can be exploited as legal clues, with important repercussions on public security and citizens’ rights. The datum does not exist in nature, being it a consequence of the human analysis of a given phenomenon. In fact, data extraction is based on explicit and implicit theories implemented by the researcher within the application of specific frameworks. Researchers and professionals working on empiric data should be more aware of these underlined processes in order to avoid data misuse and, indeed, maximize results. In this paper, we will briefly address the issue of the speech data epistemology with a particular focus on the interdisciplinary approach required in forensics (e.g. between linguistics and engineering), by discussing examples from Italian real cases. Moreover, it must be clarified what different experts (e.g., lawyers vs. linguists) mean as datum in forensic research.File | Dimensione | Formato | |
