POSTVOCALIC /r/-DELETION IN DUTCH:MORE EXPERIMENTAL EVIDENCE
Catia Cucchiarini, Henk van den Heuvel · 1999
In this study we investigate three properties of the left vowel in Dutch by checking how often /r/-deletion occurred in a large context which we hypothesize to underlie deletion of /r/ in spontaneous speech corpus (214,102 words). To this end a postvocalic, preconsonantal position in Dutch spontaneous speech: continuous speech recognizer (CSR) in forced recognition mode vowel type (schwa, full vowel), vowel length (long, short) and was used. The CSR had the task to decide whether /r/-deletion was lexical stress (+,-). For each of five categories 90 instances with applied or not in a word. possible /r/-realizations were extracted from a large speech database The accuracy of forced recognition in selecting the correct containing man-machine dialogues in an automatic train-table variant was checked in an experiment [6] in which the CSR's inquiry system. The frequency of /r/-deletions in these 450 cases responses were compared with those of nine expert listeners who was investigated on th...
