COMPARE — Systematic comparisons of spectral voice patterns

Computes the similarity between spectral voice patterns in intra-individual comparisons (repeated assessments on the same individual) and inter-individual comparisons (assessments on different, unrelated/related individuals). The program particularly allows one to analyse the similarity between voice patterns as a function of frequency at a quartertone resolution over the frequency range of 64-8192 Hz, so that frequency bands can be weighted in such a way that the intra-individual similarity is maximized while the inter-individual similarity is minimized. The effects of this optimization can be quantified through the false-negative and false-positive classification errors in a computerized recognition of person test (CRP-test).
