An international investigation of forensic speaker comparison practices

The results of the first international survey on
forensic speaker comparison practices are
presented in this paper. Thirty-four experts from
13 countries and 5 continents responded to a series
of questions concerning their practices in casework
and which features they found to be useful speaker
discriminants. Despite the responses revealing
some prominent trends, there is wide variation in
methodology, importance assigned to particular
speech features, and choice of framework for
expressing conclusions.
