Abstract

There is a long-standing debate on the relevant articulatory dimensions for describing vowel production. In the absence of a theoretical or methodological consensus, different articulatory studies of vowels rely on different measures, which leads to lack of comparability between different sets of results. This paper addresses the problem of how to parametrise the tongue measurements relevant to vowels, obtained from midsagittal articulatory imaging. We focus on the lax vowels subsystem in Northern Anglo-English. A range of measures quantifying tongue position, height, and shape are extracted from an ultrasound dataset representing 40 speakers. These measures are compared, based on how well they capture the lingual contrast between different vowels, how stable they are across different speakers, and how intercorrelated they are. The results suggest that different measures are preferred for different vowels, which supports a multi-dimensional approach in quantifying vowel articulation.

元音发音的维数降低:来自北方盎格鲁英语中元音松弛的证据。
关于描述元音产生的相关发音维度存在长期争论。在缺乏理论或方法共识的情况下,元音的不同发音研究依赖于不同的测量方法,这导致不同结果集之间缺乏可比性。本文解决了如何参数化舌测量相关的元音,从中矢状关节成像获得的问题。我们着重研究了北方盎格鲁英语中的弱元音子系统。从40个说话人的超声波数据集中提取了一系列量化舌头位置、高度和形状的测量方法。对这些测量进行比较的基础是,它们捕捉不同元音之间的语言对比的程度,它们在不同说话者之间的稳定程度,以及它们之间的相互关联程度。结果表明,不同的元音采用不同的测量方法,这支持了元音发音量化的多维方法。
