The Scottish Vowel Length Rule (SVLR) is a special feature of Scottish English phonology and is said to contrast with the Voicing Effect (VE), the vowel timing pattern found in most other varieties of English. In this in-depth work, Andreas Weilinghoff employs some of the latest speech technology as well as advanced methods in inferential statistics to reveal not only the complex patterns of vowel duration in Scottish English but also how quantity patterns observed in production experiments change in naturally occurring speech. This book brings together different disciplinary areas from Scottish English studies, Sociophonetics to Corpus Linguistics and Computational Linguistics.
