Quantitative Comparison Method of Forensic Voice Evidence
In this paper, the scientific demands of forensic evidence were introduced. The quantitative analysis methods and processes of forensic evidence were proposed, and the feasible quantitative examination methods of evidence that match the admission criterion of scientific evidence were summarized. In addition, taking voice evidence for example, the datadriven calculation methods of evidence stren...
متن کاملDatabase selection for forensic voice comparison
Defining the relevant population to sample is an important issue in data-based implementation of the likelihood-ratio framework for forensic voice comparison. We present a logical argument that because an investigator or prosecutor only submits suspect and offender recordings for forensic analysis if they sound sufficiently similar to each other, the appropriate defense hypothesis for the foren...
متن کاملForensic Voice Comparison Using Chinese /iau/
An acoustic-phonetic forensic-voice-comparison system extracted information from the formant trajectories of tokens of Standard Chinese /iau/. When this information was added to a generic automatic forensic-voice-comparison system, which did not itself exploit acoustic-phonetic information, there was a substantial improvement in system validity but a decline in system reliability.
متن کاملAutomatic forensic voice comparison (Automatischer forensischer Stimmenvergleich)
Automatic speaker recognition systems have been developed and constantly improved during recent decades. However, even though these systems have been applied to the task of forensic voice comparison since the early 2000s, their behaviour under realistic forensic conditions has not often been thoroughly tested since then. Additionally, the application of these systems is not standardised and is ...
متن کاملSPES: The BKA Forensic Automatic Voice Comparison System
The BKA voice comparison system SPES is designed for forensic examination of speech recordings. The classical GMMUBM framework based on MAP adaptation as described by Reynolds et al. [1] is extended by the generation of recording adapted background models (RABMs). We present results from experiments using real case data. These results show how the most critical properties of real case recording...
