The overarching objective of our proposal is to further our understanding of the inner temporal dynamics of diphthongs across a range of diphthongs and for two different languages. Despite diphthongs being part of many vowel inventories in the world’s languages, there is a dearth of knowledge about what the defining characteristics of diphthongs are and how to capture theoretically and empirically their oscillating identity between unity (single unit) and duality (sequence of two units). Our proposed work will capitalize on the diphthong inventories of Tyrolean and Sardinian, as well as on recent advances in data quantification methods in the phonetic sciences to significantly deepen our knowledge of diphthong dynamics in speech production. Tyrolean and Sardinian are well suited as objects of investigation due to their rich but contrasting diphthong inventories comprising presumably structurally different diphthong types. Our work carries innovative potential in several aspects: For one, we provide the first comprehensive phonetic description of the vowel inventories of two phonetically understudied languages, including their numerous diphthongs. We will acoustically record the vowel inventory (monophthongs and diphthongs) for Tyrolean as spoken in the city of Meran and for the Cagliari Campidanese variety of Sardinian, an endangered language. We will record 40 speakers per language, divided into two age groups to be able to observe possible ongoing sound changes. Secondly, we will exploit state-of-the art statistical techniques for the analysis of time series data to study the inner temporal structure of the diphthongs of these two languages under varying prosodic conditions. These analyses are designed to open new vistas on the question whether diphthongs can be understood as a sequence of two vocalic gestures, coarticulated to varying degrees, or whether the target of diphthong production is a dynamic transitional movement through the vowel space. Thirdly, we will make available to the scientific community a database with our recordings, as well as speech technological tools – trained models for automatic segmentation – that will facilitate future research on these languages. Expanding our knowledge of diphthong dynamics across languages, and their relation to both monophthongs and vowel sequences (hiatus) is crucial to deepening our theoretical and empirical understanding of (1) types of vowels and synchronic vowel systems, (2) the evolutionary paths vowel systems take diachronically, as well as (3) theories of speech production, which rarely deal with diphthongs. Our Italian-German research team is well poised to tackle the proposed investigation into the rich vowel systems of Tyrolean and Sardinian by bringing together experts on speech production, language variation, and dialectology.

我们的建议的总体目标是进一步了解内部的时间动态的双元音在一系列的双元音和两种不同的语言。尽管双元音是世界语言中许多元音的一部分，但人们对双元音的定义特征是什么以及如何从理论和经验上捕捉它们在统一性（单个单位）和二元性（两个单位的序列）之间的振荡身份缺乏了解。我们建议的工作将利用蒂罗尔和撒丁岛的双元音库存，以及在语音科学的数据量化方法的最新进展，显着加深我们的双元音动态语音生产的知识。提洛尔语和撒丁岛语非常适合作为研究对象，因为它们丰富但对比鲜明的双元音库存包括可能结构上不同的双元音类型。我们的工作在几个方面具有创新的潜力：首先，我们提供了第一个全面的语音描述的元音库存的两个语音研究不足的语言，包括他们众多的双元音。我们将声学记录的元音库存（单元音和双元音）的蒂罗尔人说的城市梅朗和卡利亚里坎皮达语品种的撒丁岛，一种濒危语言。我们将记录每种语言的40名发言者，分为两个年龄组，以便能够观察可能的持续声音变化。其次，我们将利用国家的最先进的统计技术分析的时间序列数据，研究这两种语言的双元音在不同的韵律条件下的内部时间结构。这些分析的目的是打开新的远景的问题是否可以理解为一个序列的两个元音的手势，cocarticulated到不同程度，或是否双元音生产的目标是一个动态的过渡运动，通过元音空间。第三，我们将向科学界提供一个数据库，其中包含我们的录音，以及语音技术工具-用于自动分割的训练模型-这将有助于未来对这些语言的研究。扩展我们对跨语言的双元音动态及其与单元音和元音序列（间隙）的关系的知识，对于加深我们对以下方面的理论和经验理解至关重要：（1）元音和共时元音系统的类型，（2）元音系统的历时演变路径，以及（3）很少涉及双元音的言语产生理论。我们的意大利-德国研究团队已经做好准备，通过汇集语音产生，语言变异和方言学方面的专家，来解决对蒂罗尔和撒丁岛丰富元音系统的拟议调查。
