摘要在对称的VCV序列中,双唇塞音常表现为舌的压低。这种现象的原因,有时被称为“低谷效应”,是未知的。然而,它可能对研究言语事件的时变方面有重要的意义。超声是一种非侵入性的技术,它使我们能够对舌头的形状进行真实的成像,并测量在VCV序列的C中发生的实际舌头位移。对10名英国英语使用者进行了5次V1 CV 2对称序列的重复测试,其中包括双唇塞音/B,p/。结果显示,不同受试者不仅舌位移方向和程度不同,而且舌轮廓形态也不同。本研究证明了超声波作为语音研究技术的有效性,使得对来自多个受试者的大量数据进行舌面运动分析成为可能。
Abstract Bilabial stops often show a lowering of the tongue in symmetrical VCVsequences. The causes of this phenomenon, sometimes called the ‘trough effect’,are unknown. However, it could have important implications for the study of timevaryingaspects of speech events. Ultrasound is a non-invasive technique that hasallowed us to image the shape of the tongue in real time and measure the actualtongue displacement that occurs in the C of a VCV sequence. Five repetitions ofsymmetrical V1CV2 sequences with the bilabial stops /b, p/ were obtained from 10British English speakers. Results showed not only differences in the direction anddegree of the tongue displacement but also differences in the tongue contour configurationbetween subjects. This study demonstrates the effectiveness of ultrasoundas a technique in phonetic research, making possible the analysis of tonguesurface movement for large amounts of data from multiple subjects.
