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.
