Prosody has been shown to affect the articulatory movements of vowels and consonants systematically. At phrase boundaries and under accentuation, longer and larger movements of the tongue and the jaw can be attested. These results indicate that prosody is not only characterized by tonal aspects, e.g., intonation contours, but significantly shaped by a multitude of phonetic cues. Dynamical modelling approaches concerned with the effects on articulation have started to emerge using the concept of prosodic modulation gestures. Modulation gestures do not have constriction targets but affect the constriction gestures for the production of vowels and consonants during the mutual time of activation. While most of the models using modulation gestures concentrate on the effects of prosodic boundaries on articulation, a lot of work remains to be done with regard to the modelling of prosodic prominence. The project fills this gap in developing a dynamical model of phrase-level prominence effects on articulation using modulation gestures, based on experimental investigations. It aims at providing an adequate characterization of modulation gestures for prominence. While most studies on modulations at prosodic boundaries assume temporal modifications, e.g., slower movements, prominence-induced effects on articulation have also been found to be spatial, e.g., larger movements. The project addresses the question as to whether the spatial effects can be described as by-products of temporal modifications or whether they constitute a separate dimension of prosodic modulation. Moreover, studies on intonation indicate that the relation between multiple prominences within one phrase plays a major role. Important pragmatic meanings are not exclusively encoded locally but seem to be distributed over the whole phrase. The project therefore concentrates on the modelling of prosodic strength relations between multiple elements in one phrase and the gradiency of prosodic modulations. It uses the approach of coupled oscillations to describe effects in hierarchically organized linguistic structures. The dynamical modelling approach does not only allow for the interaction between multiple elements in the hierarchy but also captures gradual modifications. In consequence, it is able to model prosodic effects beyond the dichotomy of accented vs. unaccented. A further aim of the project is to investigate the interplay of articulatory and tonal factors. It will focus on how prosodic modulations affect supra-laryngeal articulation gestures (for consonants and vowels) and tonal gestures (for pitch accents) at the same time.

韵律已被证明会系统地影响元音和辅音的发音运动。在短语边界和强调下，可以证明舌头和下颌的更长和更大的运动。这些结果表明，韵律不仅具有音调方面的特征，例如语调轮廓，而且由多种语音提示显着塑造。与韵律调制手势的概念有关，与对发音影响有关的动态建模方法已开始出现。调制手势没有收缩目标，而是会影响相互激活期间元音和辅音的收缩手势。尽管使用调制手势的大多数模型都集中在韵律边界对发音的影响上，但关于韵律突出的建模，许多工作还有许多工作要做。基于实验研究，该项目填补了这一空白，以使用调制手势开发出对关节效果的动态模型。它旨在为调制手势提供足够的表征。尽管大多数关于韵律边界调制的研究都假设时间修饰，例如运动较慢，但也发现了突出性诱导的对关节的影响是空间的，例如，较大的运动。该项目解决了一个问题，即是否可以将空间效应描述为时间修改的副产品，或者它们是否构成韵律调制的单独维度。此外，对语调的研究表明，一个短语中多个突出之间的关系起着主要作用。重要的务实含义不是在本地编码的，而是在整个短语中分布。因此，该项目集中于一个短语中多个元素之间的韵律强度关系的建模和韵律调制的梯度。它使用耦合振荡的方法来描述层次组织的语言结构中的影响。动态建模方法不仅允许层次结构中多个元素之间的相互作用，而且还允许捕获逐渐修改。因此，它能够模拟超出重音和未重新构成二分法的韵律作用。该项目的进一步目的是研究关节和音调因素的相互作用。它将重点介绍韵律调制如何同时影响超乳腺发音手势（用于辅音和元音）和音调手势（用于音高的口音）。
