Forensic automatic speaker recognition
Automatic speaker recognition technology appears to have reached a sufficient level of maturity for realistic application in the field of forensic science. However, there are key issues to be solved before the forensic community will accept its use as an investigative assistant or as evidence in actual criminal cases. To assess the state of the technology, the Federal Bureau of Investigation (F...
متن کاملAuditory-instrumental forensic speaker recognition
The most prominent part in forensic speech and audio processing is speaker recognition. In the world a number of approaches to forensic speaker recognition (FSR) have been developed, that are different in terms of technical procedures, methodology, instrumentation and also in terms of the probability scale on which the final conclusion is based. The BKA‘s approach to speaker recognition is a co...
متن کاملForensic speaker recognition: An evidence odyssey – Summary
The goal of a technology evaluation is to compare competing algorithms from a single technology. Testing of all algorithms is done on a standardized database collected by a “universal” sensor. Nonetheless, performance against this database will depend upon both the environment and the population in which it was collected. Because the database is fixed, results of technology tests are repeatable...
متن کاملForensic automatic speaker recognition: fiction or science?
Hollywood films and CSI-like movies show a technology landscape far from real, both in forensic speaker recognition and other identification-of-the-source forensic areas. Lay persons are used to good-looking scientist-and-investigators performing voice identifications (”we got a match!”) or smart fancy devices producing voice transformations causing one actor to instantaneously talk with the vo...
متن کاملEstimated Intra-Speaker Variability Boundaries in Forensic Speaker Recognition Casework
Current automatic forensic speaker recognition algorithms are known to be highly dependent on matched reference data for producing statistically reliable outcomes. In day-to-day forensic casework, this data is often not available. This paper addresses this problem by introducing a data-driven modular method which does not require precise reference data. Results are more general and given as p-v...
