This study investigates non-native speech rhythm in German. Three native speakers and 18 learners of German with three different native languages were recorded reading and re-telling a story. Vowel reduction and deletion was analyzed in one particular type of German suffix. Speech rhythm was investigated with the syllable ratio, a new measurement which determines the mean ratio of durational relationships between adjacent syllables of different types. Results show significant differences between native and non-native speech rhythm in terms of vowel reduction and deletion and the durational ratio between non-reduced and reduced syllables. The non-native speech rhythm tends to differ in the direction predicted by the rhythmic structure of the L1. However, independent of the native language, non-native rhythm varies with the type of speech (read speech versus story-telling).
