1. A system, comprising:
an output interface; and
one or more processors, configured to cooperatively carry out a process that includes:
mapping a test speech sample, which was produced by a subject while a physiological state of the subject was unknown, to a reference speech sample, which was produced in a known physiological state,
based on the mapping, computing a distance between the test speech sample and the reference speech sample, and
in response to the distance, communicating, via the output interface, an output indicating the physiological state of the subject while the test speech sample was produced,
wherein the reference speech sample was divided into multiple reference-sample segments based on differences in acoustic properties between each pair of successive ones of the reference-sample segments,
wherein mapping the test speech sample to the reference speech sample includes:
dividing the test speech sample into multiple test-sample segments based on differences in the acoustic properties between each pair of successive ones of the test-sample segments, and
mapping at least some of the test-sample segments to corresponding ones of the reference-sample segments, and
wherein computing the distance includes computing the distance based on respective local distances between the mapped test-sample segments and the corresponding ones of the reference-sample segments.
