Consonant perception varies substantially even across repeated tokens of one talker.

Evidence

The investigation of different sources of variability in Sect. 3 indicated that any considered difference in the stimuli produced a measurable effect. The observed perceptual variability across talkers is well established in the related literature (e.g., Phatak et al. 2008 ); the equally large variability within talkers had not yet been demonstrated. — Dijk, Pim van, Physiology, Psychoacoustics and…, 5575

• XREF: Challenges the assumption that within-talker tokens are interchangeable; relevant to the reading-goal focus on what normal hearing actually processes beyond phonetic identity.
