The overall goal of this research is to improve our understanding of inter-speaker variability in articulatory control of speech. Along with the theoretical importance, this knowledge has a number of important practical implications. These include the development of a speaker-independent model for speech recognition and synthesis and creation of a comprehensive speech movement reference database that can be used in cross-linguistic and speech production training studies. *** The specific focus of this application is on the anatomical factors underlying speech production variability. This line of enquiry is motivated by the lack of agreement in the literature on the existence of a relationship between factors such as oral cavity and tongue size, skull morphology and jaw length with speech and oral movement characteristics. In this study we will pursue the following questions: (1) Can a speaker be classified based on measures of their oral anatomy? (2) Do speakers with similar anatomies show similar articulatory movement patterns in speech? and (3) Does anatomic variability contribute to differences in tongue-jaw coordination and articulatory strategies during speaking. *** Anatomic data will be obtained from 60 adults using computer-aided lateral cephalometry. A large corpus of speech of different complexity (e.g., syllable to phrase to paragraph), style (e.g., fast, slow, clear) and non-speech tasks (e.g., maximum mouth opening) will be recorded using electromagnetic articulography. Anatomic measurements (e.g., tongue size, jaw and mandible size and shape) will be used in a cluster analysis to classify speakers into groups. Kinematic measures will include those focused on articulatory movements as a whole (e.g., articulatory working space, motion dynamic range), sound specific (e.g., articulatory position variability), and syllable/phrase specific measures (e.g., average movement speed, peak speed, movement duration, and range). They will be correlated to the anatomic measurements and compared between speakers in different anatomic groups. *** This research will be among first to comprehensively examine the variability in the anatomical dimensions of articulators and their role in speech movement variability in a large cohort of speakers. The outcome of this work will lead to identification of “canonical” articulatory parameters in speech production common across speakers and facilitate the development of the speaker-independent articulatory model of speech production.

本研究的总体目标是提高我们对说话人间变异性的理解， 发音的控制。沿着理论上的重要性，这方面的知识有许多 重要的实际影响。 其中包括开发一个独立于说话者的语音识别和合成模型，以及创建一个全面的语音运动参考数据库，可用于跨语言和语音生成培训研究。*** 该应用程序的具体重点是对语音产生变异性的解剖因素。这条调查线的动机是缺乏一致的文献中存在的因素之间的关系，如口腔和舌头的大小，头骨形态和下颌长度与语音和口腔运动特征。 在本研究中，我们将探讨以下问题：（1）是否可以根据口腔解剖的测量结果对说话者进行分类？(2)具有相似解剖结构的说话者在言语中是否表现出相似的发音运动模式？（3）解剖变异是否会导致说话时舌颌协调和发音策略的差异。*** 将使用计算机辅助头颅侧位测量法从60名成人中获得解剖数据。不同复杂度的大型语音语料库（例如，音节到短语到段落），风格（例如，快、慢、清晰）和非语音任务（例如，最大张口度）将使用电磁关节造影术记录。解剖测量（例如，舌头大小、颚和下颌骨大小和形状）将用于聚类分析以将说话者分类成组。 运动学测量将包括那些集中于整体发音运动的测量（例如，发音工作空间，运动动态范围），声音特定（例如，发音位置可变性），以及音节/短语特定测量（例如，平均移动速度、峰值速度、移动持续时间和范围）。它们将与解剖测量相关联，并在不同解剖组的扬声器之间进行比较。*** 这项研究将是第一个全面研究的变异性的解剖尺寸的发音和他们的作用，在一个大的发言者群体的语音运动的变化。这项工作的结果将导致识别的“规范”发音参数在语音生产中常见的扬声器和促进发展的扬声器独立的发音模型的语音生产。
