Speech phonemes reduce to 18 articulatory-acoustic features in a linear mapping

Evidence

The phonetic features (Fea) encoding is a linear mapping of the phonetic representation into a space of 18 features (Mesgarani et al. 2014 ), which describe specific articulatory and acoustic properties of the speech phonetic content (Chomsky and Halle 1968 ). In particular, the chosen features are related to the manner and place of articulation, to the voicing of a consonant, and to the backness of a vowel. — Dijk, Pim van, Physiology, Psychoacoustics and…, 4480
