Physiological effects on stop consonant voicing
TLDR
In this article, an electrical analog of vocal tract aerodynamics was used to study the probable effects of place of articulation and syllable stress on closure voicing offset, allowing variation of subglottal pressure, glottal area, supralaryngeal cavity volume, wall mechanics, and oral constriction geometry.Abstract:
Voiced and voiceless stops in initial position are known to differ in Voice Onset Time; they may also differ in closure duration and the duration of closure voicing. Besides the voicing distinction, such factors as the position of the stop in a word or utterance, the stop's place of articulation, and the stress of adjacent syllables will also affect these measures. Data from the literature have been extended with new acoustic measurements for English, Swedish, and other languages. While there is some variation across languages, general patterns, which might be attributable to vocal tract physiology, can be identified. In an attempt to account for these patterns, an electrical analog of vocal tract aerodynamics can be used to study the probable effects of place of articulation and syllable stress on closure voicing offset. The model allows variation of subglottal pressure, glottal area, supralaryngeal cavity volume, wall mechanics, and oral constriction geometry. The extent to which these variables determi...read more

TL;DR: The acoustic properties VOT, total voiceless interval, %voicing during closure, nasal energy minimum, and to a lesser extent stop burst energy and voicing into closure, were found to vary with prosodic position and, in some cases, to correlate with linguopalatal contact.

On the naturalness of stop consonant voicing
TL;DR: The formal theory of markedness, developed by Trubetzkoy and Jakobson in the early 1930's, and extended by Chomsky and Halle (1968) represents an attempt to deal with this problem as mentioned in this paper.

Prosodic influences on consonant production in Dutch: Effects of prosodic boundaries, phrasal accent and lexical stress
Taehong Cho,James M. McQueen +1 more
TL;DR: The patterns found in acoustic measurements of these utterances indicate that the low-level phonetic implementation of all four consonants is modulated by prosodic structure, and suggests that prosodically driven phonetic realization is bounded by language-specific constraints on how phonetic features are specified with phonetics.

TL;DR: In this article, the authors present experimental results that support the view that German has underlying [spread glottis] stops, not [voice] stops and that the intervocalic voiced stops arise because of passive voicing of the non-spreadglottis stops.
