Forensic speaker recognition: Based on text analysis of transcribed speech fragments

Currently, speaker recognition research is mainly based on phonetics and speech signal processing. This research addresses speaker recognition from a new perspective, analysing the transcription of a fragment of speech with text analysis methods. Since text analysis is based on the transcription text only, it can be assumed independent from...

Mathematics as a secret weapon against criminals: Employing score-based likelihood ratio systems for the comparison of handwriting and studying their quality of performance

In this report a new approach to (forensic) handwriting analysis is presented; score-based likelihood ratio (SLR) systems are employed and their quality of performance is studied. These systems compare elements of handwriting based on their characteristics and give an insight into the degree of uncertainty of the statement that two writings have...
