Abstract

This study examines trans-vocalic CVC coarticulation of the coronal (dental, alveolar, retroflex and (alveo-)palatal) stop, nasal and lateral consonants of Arrernte, an Aboriginal language of Central Australia, using electro-palatographic (EPG) recordings of continuous speech. Coronal consonants are known to be more coarticulatorily resistant than peripheral consonants such as bilabials and velars, and this study teases out the coarticulatory differences between these four coronal places of articulation. Results confirm findings from previous studies that laminal consonants (dental and alveo-palatal) are broadly more coarticulatorily aggressive than apical consonants (alveolars and retroflexes), with the alveolars the least resistant to coarticulation. Dental consonants exert fronting effects on both preceding and following consonants, a result consistent with previous acoustic results for these sounds. Similarly, alveo-palatal consonants show both anticipatory and carryover effects, though their exact coarticulatory effect depends on the affected consonant place and manner. The retroflex consonants exert strong fronting effects on the following consonant, and it is suggested that this is due to the anterior release of retroflexes following ballistic forward movement during closure. There is also some evidence of a retraction effect of retroflexes on preceding consonants. Despite this evidence of coarticulatory aggression, retroflexes are particularly affected by preceding and following palatals: in these cases, the retroflex articulation becomes more forward, and dorsal contact for the retroflex is increased. In sum, by examining speech in an understudied language, we learn that there are still greater complexities in the co-ordination of consonants produced using the tongue tip and blade.

中耳区冠状辅音的跨音协同发音:电腭图研究
本研究利用电腭图(EPG)记录的连续语音,研究了澳大利亚中部土著语言Arrernte的冠状(牙槽、牙槽、反折和(牙槽-)腭)止音、鼻辅音和侧辅音的跨语音CVC协同发音。冠状辅音被认为比周围辅音如双唇音和舌尖音更具有协同发音的抗性,本研究梳理了这四个冠状发音部位之间的协同发音差异。结果证实了先前的研究结果,即板状辅音(牙状辅音和牙槽-腭状辅音)比根尖辅音(肺泡辅音和后旋辅音)更具有协同发音的攻击性,而肺泡辅音对协同发音的抵抗力最低。牙辅音对前辅音和后辅音都有正面作用,结果与这些音之前的声学结果一致。同样,牙槽-腭辅音也表现出预期和延续的效果,尽管它们确切的协同发音效果取决于受影响的辅音位置和发音方式。后旋辅音对后面的辅音有很强的前置作用,这可能是由于闭锁时随着弹道向前运动后前旋释放所致。也有一些证据表明,对前辅音的反旋有缩回作用。尽管有协同关节攻击的证据,但后屈尤其受到前后腭的影响:在这些情况下,后屈关节变得更前,后屈关节的背侧接触增加。总之,通过研究一门未被充分研究的语言的语音,我们了解到使用舌尖和舌叶发出的辅音的协调仍然存在更大的复杂性。

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
