Abstract This article presents a dictionary-based study of vowel reduction and preservation in British English in initial pretonic position and intertonic position. The different variables which have been claimed to influence those processes are tested on a data set of over 4,500 words using regression analyses. Our results confirm the significant effects of syllable structure, position of the vowel, word frequency and opaque prefixation. They also provide weak evidence for other factors such as vowel features and the existence of a base in which the vowel bears a stress, although no clear effects of word segmentability could be found. We also report new findings, as we find that foreign words reduce less than non-foreign words; we find that +back vowels reduce less than −back vowels in initial pretonic position; and we find a difference in behaviour for vowels followed by /sC/ clusters between non-derived words and stress-shifted derivatives.
