The perception of vowel length and quality in German

Based on an unpublished dissertation titled Perceptual parameters of vowel length and quality in standard New High German (University of Colorado, 1970). The experiment described is regarded to be an innovative departure in the investigation of vowel perception: vowels are used in which the qualitative and durational aspects have been manipulated quite naturally. The topic has aroused considerable interest. Several articles on the significance and application of the test have already been written.
