  abstract = {In a recent experiment concerned with diachronic u:-fronting in Standard Southern British, it was shown both that the u: category boundary was perceptually retracted for older compared with younger listeners of this variety, and that they compensated perceptually to a greater extent for the coarticulatory fronting effects of the preceding consonant on u: in words like used. In the present study, these perceptual differences were related to the same speakers' productions of words containing a u: nucleus in a fronting (e.g., 'used') and non-fronting (e.g., 'swoop') contexts. The relative acoustic distance of u: between front and back vowels was measured in a three-dimensional space formed by applying the discrete-cosine-transformation to the entire F2-trajectory shape separately for each speaker. Compatibly with their perceptual responses, older listeners had a more retracted u: on this measure and exhibited a greater coarticulatory influence of the preceding consonant. The mechanism of this sound change is considered both from the point of view of a shift in the perceptual compensation for coarticulation and recent developments in episodic models of speech perception.},
