Abstract

The present letter to the editor is one in a series of publications discussing the formulation of hypotheses (propositions) for the evaluation of strength of forensic evidence. In particular, the discussion focusses on the issue of what information may be used to define the relevant population specified as part of the different-speaker hypothesis in forensic voice comparison. The previous publications in the series are: Hicks et al. 2015 <http://dx.doi.org/10.1016/j.scijus.2015.06.008>; Morrison et al. (2016) <http://dx.doi.org/10.1016/j.scijus.2016.07.002>; Hicks et al. (2017) <http://dx.doi.org/10.1016/j.scijus.2017.04.005>. The latter letter to the editor mostly resolves the apparent disagreement between the two groups of authors. We briefly discuss one outstanding point of apparent disagreement, and attempt to correct a misinterpretation of our earlier remarks. We believe that at this point there is no actual disagreement, and that both groups of authors are calling for greater collaboration in order to reduce the likelihood of future misunderstandings.
