Stops in Swiss German contrast only in quantity in all word positions; aspiration and voicing play no role. As in most languages with consonant quantity contrast, geminate stops are produced with significantly longer closure duration (CD) than singletons in an intersonorant context. This holds word medially as well as phrase medially, e.g., [oni tto:s] "without roar" versus [oni to:s] "without can." Since the stops are voiceless, no CD cue distinguishes geminates from singletons phrase… Expand
Closure duration as an acoustic correlate of the word-initial singleton/geminate consonant contrast in Kelantan Malay
TLDR
Results show that closure duration is a robust acoustic correlate of the consonant contrast in KM, i.e., word-initial geminates in KM are always associated with significantly longer closure duration than their corresponding singletons. Expand
"Fake" gemination in suffixed words and compounds in English and German.
TLDR
Analysis of the acoustics of native speakers reading suffixed and compound words containing both fake geminate and non-geminate consonants in similar phonological environments suggests that English and German speakers articulate fake geminates with acoustic characteristics similar to those found in languages with an underlying length contrast, despite no longer displaying the contrast morpheme-internally.

Obstruent voicing effects on F0, but without voicing: Phonetic correlates of Swiss German lenis, fortis, and aspirated stops
TLDR
A detailed study of voice onset time (VOT), closure duration, and obstruent F0 effects in Zurich Swiss German supports the view that the phonetic basis of voicing and related distinctions involves complex interactions of timing and articulatory gestures that cannot always be characterised in terms of a simple VOT continuum.

TEMPORAL ORGANIZATION OF VOWEL PLUS STOP SEQUENCES IN PRODUCTION AND PERCEPTION: EVIDENCE FROM THE THREE MAJOR VARIETIES OF GERMAN
This study investigated cross-linguistically the temporal organization of short vs. long vowels (V vs. V:) with following lenis vs. fortis (C vs. C:) stops in disyllabic trochees in the three majorExpand
Durational correlates of singleton-geminate contrast in Hungarian voiceless stops
TLDR
Differences among geminate types are evince: fake geminates are produced with tendentiously longer durations than underlying and true derived geminate, which result suggests closer similarity between the two latter types. Expand
Durational properties of emphatic consonants in Japanese ∗
Languages that exploit a duration-based length contrast usually make use of a binary contrast; i.e. short vs. long. In colloquial Japanese, however, speakers can use consonant lengthening forExpand
Durational properties of emphatically lengthened consonants in Japanese
Languages can make use of phonetic duration to signal two kinds of meanings. The first is a lexical, phonological contrast. For example, in Japanese [kata] with a short [t] means ‘frame’ and [katta]Expand
Durational Correlates of Word-initial Voiceless Geminate Stops: The Case of Kelantan Malay
TLDR
An acoustic phonetic analysis examining two acoustic parameters: closure duration and voice onset time finds closure duration to be the most robust acoustic correlate for the singleton-geminate contrast in Kelantan Malay. Expand

This paper presents evidence for two claims: (a) that the underlying contrast between stops in Swiss German dialects is based purely on quantity and (b) that the duration of the stop closure is itsExpand

Swiss German dialects have contrastive singleton and geminate voiceless stop consonants in all word positions. This contrast is acoustically manifested in short and long closure duration, whichExpand
Domain-initial articulatory strengthening in four languages
TLDR
This paper is about one way in which prosody affects individual speech segments, with segmental phonetics showing a perhaps surprising sensitivity to higher-level linguistic structure, and shows that phonetic properties of individual segments depend on their prosodic position, or position in prosodic structure.

Prosodic influences on consonant production in Dutch: Effects of prosodic boundaries, phrasal accent and lexical stress
TLDR
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.

TLDR
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. Expand
