“…They thus proposed that invariances characterizing the relation between syllabic organization and phonetics are dynamic as opposed to static. Gafos et al (2014) pursued further analysis of the experimental and computational result of Shaw et al (2011). In their study, the statistics of syllabic organization were expressed in equations involving estimates of continuous phonetic parameters expressing the timing of consonants and vowels: consonantal plateau durations, vowel durations, and their variances.…”

Previous studies suggest that there are special timing relations in syllable onsets. The consonants are assumed to be timed, on the one hand, with the vocalic nucleus and, on the other hand, with each other. These competing timing relations result in the C-center effect. However, the C-center effect has not consistently been found in languages with complex onsets. Moreover, it has occasionally been found in languages disallowing complex onsets. The present study investigates onset timing in German while discussing alternative explanations (not related to bonding) for the timing patterns observed. Six German speakers were recorded via Electromagnetic Articulography. The corpus contained items with four clusters (/sk/, /kv/, /gl/, and /pl/). The clusters occur in word-initial position, word-medial position, and across a word boundary preceding different vowels. The results suggest that segmental properties (i.e., oral-laryngeal coordination, coarticulatory resistance) determine the observed timing patterns, and specifically the absence or presence of the C-center effect.

“…Even though two different phonological syllable parses (i.e., simple and complex onset parse) are assumed to be triggered by the speakers' grammatical knowledge, we expect to find naturally-induced variation on the phonetic surface patters. As mentioned before, this type of variation can be systematically triggered by factors such as prosodic structure, segmental context, and speaker-specificity (Mücke et al, 2017;Hermes et al, 2017;Gafos et al, 2014). The challenge of flexibility and stability is important for language production and it can be found within and across languages.…”

“…Both strategies affect temporal and spatial properties of articulatory speech movements and the related acoustic output. Thus, we always deal with surface patterns which are affected by prosodic variation, segmental effects, or speaker-specific behaviour (inter alia Mücke, Hermes & Cho, 2017;Hermes, Mücke, & Auris, 2017;Gafos, Charlow, Shaw, & Hoole, 2014). However, the mediation between the linguistic and physical control systems should imply efficient timing patterns which increase either prosodic/paradigmatic contrast or decrease the costs of the physical control system.…”

This study investigated syllable coordination patterns in Essential Tremor (ET) patients treated with Deep Brain Stimulation (DBS) by using electromagnetic articulography. We analyzed articulatory timing patterns for nine ET patients with activated and inactivated DBS and compared them to a group of healthy age-matched controls. We focused on timing patterns among gestures in syllables with low and high complexity in natural sentence production (simple CV versus complex CCV syllables). These articulatory patterns were interpreted in the framework of a coupled oscillator planning model of speech timing. In simple CV syllables, ET patients did show a similar coordination pattern to healthy control speakers. However, when complexity increased, the patients showed deviant coordination patterns for complex CCV syllables. These deviant patterns even aggravated under activated stimulation. We were able to show that the behavior of the speech system changes when the stimulation was activated, inducing a change in the dynamical system the ET patients have to adapt to. We conclude that coordination problems are not categorical but gradient in nature, pointing to the fact that there are dynamic mechanisms of regulation behind phonetic realization of phonological syllable parses.

“…On the other hand, Brunner, Geng, Sotiropoulou, and Gafos' () study of initial clusters in German yields less clear results. Nevertheless, Gafos, Charlow, Shaw, and Hoole () and Shaw and Gafos () propose a stochastic modeling approach to the relationship between phonetic parameters (speech movement data) and phonological structure that provides powerful diagnostics allowing syllabification to potentially be determined in a more reliable fashion. While articulatory studies of this type will probably not end the debate on the relevance of sonority to phonological analyses, they represent a significant addition to our arsenal of tools.…”

This metastudy summarizes 264 recent experimental works involving sonority. The discussion here centers around an accompanying appendix that lists several details of each study, including the research question or hypothesis, outcome, language of focus, stimuli used to probe for the effect of sonority, methodology used to present test items and/or obtain results, participants' task, variables measured, and keywords. These metadata are presented in an Excel spreadsheet in order to give users flexibility to search and sort by details of interest, either alone or in various combinations. The overall findings of the 264 studies are naturally somewhat mixed but in general provide moderate support for the linguistic relevance of sonority.
