Sound-source differences dominate consonant perception variability more than listener uncertainty

Evidence

Motivated by the increasing evidence for a major variability in consonant perception that cannot be accounted for by the phonetic identity of the stimuli, the present study attempted to quantify some of the sources of variability that influence consonant perception. It was distinguished between source-induced variability and receiver-related variability . The former was subdivided into speechand noise-induced variability; the latter was subdivided into acrossand within-listener variability. — Dijk, Pim van, Physiology, Psychoacoustics and…, 5579

Categorization

• DEFINE: Introduces the study’s core taxonomy distinguishing source-induced (speech/noise) from receiver-related (across/within-listener) variability.
• corroborated: 6 independent passages support this claim — Dijk, Pim van, Physiology, Psychoacoustics and…, 5579
• XREF: connects to: Internal noise, not feature extraction, explains individual variation in model vowel identification; Talker identity causes more perceptual variation in consonant perception than noise waveform shifts — Dijk, Pim van, Physiology, Psychoacoustics and…, 5572; Subband and modulation power both strongly predict perceptual distances in consonant perception (+4 more)
