The aim of this project is the study of reduction phenomena in spontaneous (= non-read) Standard Dutch. Reduction is studied in mono-, bi- and trisyllabic words, especially in pronouns, suffixes and loan words. We use speech that is already collected, digitalized and transcribed for the Corpus Gesproken Nederlands (Spoken Dutch Corpus), and as a part of the VNC-project Variation in the pronunciation of Standard Dutch. The VNC-speech consists of interviews with teachers of Dutch. From the Corpus Gesproken Nederlands, three components are selected: speeches, (non-read) lectures and lessons from high school teachers (except for Dutch lessons). These three types of spontaneous speech are fully comparable: it is non-broadcast speech, produced by one speaker before an audience. A more specific aim of this project is to verify the claim that the pronunciation of highly educated speakers without linguistic training differs from the pronunciation of teachers of Dutch, who are often considered to be prototypical speakers of Standard Dutch. This project links up with the renewed interest in standard language, where variation patterns in Standard Dutch in Flanders and the Netherlands are studied from a perspective of convergence and divergence. This study is also in line with international research of variation in standard languages, e.g. in German (e.g. Germany, Austria, Switzerland) and in French (e.g. France, Canada, Belgium).
