Hi Kevin, I believe the term "objective" is referring to what is making the measurement. If responses are coming from a person then the measurements are referred to as "subjective" (i.e., perceptual). However, in this case the measurements are coming from an algorithm that transforms physical level measurements into a prediction of intelligibility. The measuring device is "objective" in the sense that you will always get the same measured value for a given set of input signals.

From my understanding perception (and perceptual evaluation) are anything but "objective"; I understand these methods to demonstrate statistical responses across the group tested, at the time of the testing. Unless this is about the intelligibility of the object being tested, in which case I think it would be "Object intelligibility measurements".
