Abstract
Abstract This paper investigates the production of dental and retroflex stops, fricatives, nasals, and laterals in the Dravidian language Kannada. This is done using articulatory contours extracted from an extensive midsagittal MRI corpus of two female Kannada speakers’ static vocal tract postures intended to capture key aspects of phonemic articulations. Articulatory modelling was used to determine a set of components responsible for the implementation of place and manner contrasts (/t̪ s̪ n̪ l̪/ vs. /ʈ ʂ ɳ ɭ/). These components included both lingual and non-lingual articulatory parameters. Constriction location and length were also determined based on articulatory contours. The results showed that the two speakers produced non-fricative retroflexes with a retracted tongue tip making a constriction behind the alveolar ridge and a characteristic convex tongue shape, yet without a retraction of the posterior portion of the tongue. Apart from the lingual parameters, place differences were also manifested by the vertical position of the larynx (lower for retroflexes). The realisation of the place contrast in sibilant fricatives was different, as /ʂ/ appeared to be produced by both speakers with a laminal alveolopalatal constriction. Manner differences were captured by various non-lingual parameters, yet being also manifested in constriction locations (more anterior for stops). These findings are discussed in the context of previous descriptive and articulatory accounts of dental-retroflex contrasts.
摘要本文研究了德拉威语卡纳达语中牙和反折止音、摩擦音、鼻音和侧音的产生。这是通过从两个女性卡纳达语使用者的静态声道姿势的广泛正中矢状核磁共振语料库中提取的发音轮廓来完成的,旨在捕捉音位发音的关键方面。发音建模用于确定一组负责执行地点和方式对比的组件(/t / s / n / l / vs / /)。这些成分包括语言和非语言发音参数。根据关节轮廓确定收缩位置和长度。结果表明,这两名说话者的舌尖在舌槽脊后收缩,舌形呈凸状,但舌后部没有收缩。除舌参数外,位置差异还表现在喉的垂直位置(后屈者较低)。在重读摩擦音中位置对比的实现是不同的,因为/ /似乎是由两个说话者用层状肺泡腭收缩产生的。各种非语言参数捕获了方式差异,但也表现在收缩位置(更前止音)。这些发现是在以前的描述性和发音的背景下讨论的牙齿-反射对比。
期刊介绍:
The Journal of the International Phonetic Association (JIPA) is a forum for work in the fields of phonetic theory and description. As well as including papers on laboratory phonetics/phonology and related topics, the journal encourages submissions on practical applications of phonetics to areas such as phonetics teaching and speech therapy, as well as the analysis of speech phenomena in relation to computer speech processing. It is especially concerned with the theory behind the International Phonetic Alphabet and discussions of the use of symbols for illustrating the phonetic structures of a wide variety of languages. JIPA now publishes online audio files to supplement written articles Published for the International Phonetic Association
