The variability of syllable patterns in Tashlhiyt Berber and Polish

Coordination patterns in Essential Tremor patients with Deep Brain Stimulation: Syllables with low and high complexity

“…However, this was not the case in our age-matched healthy control speakers. To some extent, it appears that the rightward shift was blocked, meaning that there is no change in overlap between C and V. This type of variation can be attributed to prosodic and segmental factors as being reported in Shaw et al (2011), Pastätter and Pouplier (2015), Hermes et al (2017), and Gafos et al (2019) for various languages such as German, Tashlhiyt Berber, Polish, and Moroccan Arabic. In our case, the missing rightward shift on the phonetic surface representation is likely due to effects of segmental context.…”

“…Such an increase in CV overlap is not observed in languages with simple onset coordination such as Moroccan Arabic (Shaw, Gafos, Hoole, & Zeroual, 2011) or Tashlhiyt Berber (Goldstein et al, 2007;Hermes et al, 2011). As pointed out above, these distinct syllable timing patterns are also affected by variation induced by factors such as language system, prosodic head marking, or segmental-make up (Shaw et al, 2011;Brunner, Geng, Sotiropoulou, & Gafos, 2014;Hermes et al, 2017).…”

“…The complex interplay between prosodic structure, segmental context, and phonological syllable parse affects the timing patterns of consonant and vowel articulation (Mücke et al, 2017;Hermes et al, 2017). Prosodic structure involves inter alia prosodic head marking and therefore often leads to hyperarticulation of the accented syllable to enhance prominence (especially in contrastive focus condition), while other syllables might be reduced.…”

“…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.…”
