Prosodic Peak Estimation under Segmental Perturbations

This paper is also available as a preprint.

It points out why one would normally not trust measurements of fundamental frequency peaks in human speech to be particularly meaningful. That's because the position of the peak of a function is very sensitive to any small frequency perturbation that one might add to it. That's a very general problem with measuring peaks. In this case, one might have a broad prosodic peak that one might like to measure, and the perturbation is some sort of segment-related shift in fundamental frequency.

It also includes some tests on an algorithm for finding peak positions better, but that really isn't the core of the paper.
