Whose voice is that? Challenges in forensic phonetics
In this paper, we explore speaker recognition as a process that is based partly
on analysis of phonetic and linguistic features and partly on pattern recognition
(Gestalt perception). Central to this paper is the challenge to incorporate the
dual nature of speaker recognition in forensic casework. To meet this challenge,
we propose the so-called “blind grouping” method. Blind grouping does not
require verbal-analytic terminology, but requires the expert to compare anonymised
fragments and arrange them into groups based on same-speaker and
different-speaker judgements. It allows the forensic expert to use any strategy to
reach a result, including pattern recognition and feature analysis. This method
is proposed as a supplement to the traditional auditory-acoustic method.
