本文介绍了对东尼罗语Lopit高级舌根音（ATR）的声学和发音研究结果。ATR作为一种语音学特征，在非洲元音系统中得到了广泛的证实，并且被认为与作为咽扩张的必然结果的舌根前移相关。在关于洛皮特的有限的描述性著作中，对这种对比的存在和性质有不同的看法。声学结果表明，Lopit有一个9元音系统与ATR型对比。飞行员超声结果表明，手势相关的对比是舌根推进。
This paper presents the results of an acoustic and articulatory investigation of Advanced Tongue Root (ATR) in Lopit, an Eastern Nilotic language. As a phonological feature, ATR is widely attested in African vowel systems, and is held to correlate with tongue root advancement as a corollary of pharyngeal expansion. In the limited descriptive work on Lopit, there are different views on the presence and nature of such a contrast. Acoustic results indicate that Lopit has a 9-vowel system with an ATRtype contrast. Pilot ultrasound results suggest that the gestural correlate of the contrast is one of tongue root advancement.
