Recent experiments showed that the perception of vowel length by German listeners exhibits the characteristics of categorical perception. The present study sought to find the neural activity reflecting categorical vowel length and the short-long boundary by examining the processing of non-contrastive durations and categorical length using MEG. Using(More)
The German vowel system shows a complex structure based on the interaction between vowel duration and formant structures between short and long cognates. This leads to the question how vowel duration is processed. The perception of vowel duration in German native speakers was tested by an identification test, a goodness rating and an adaptive discrimination(More)
A frequently replicated finding is that higher frequency words tend to be shorter and contain more strongly reduced vowels. However, little is known about potential differences in the articulatory gestures for high vs. low frequency words. The present study made use of electromagnetic articulography to investigate the production of two German vowels, [i](More)
Sound units play a pivotal role in cognitive models of auditory comprehension. The general consensus is that during perception listeners break down speech into auditory words and subsequently phones. Indeed, cognitive speech recognition is typically taken to be computationally intractable without phones. Here we present a computational model trained on 20(More)
The present study introduces articulography, the measurement of the position of tongue and lips during speech, as a promising method to the study of dialect variation. By using generalized additive modeling to analyze articulatory trajectories, we are able to reliably detect aggregate group differences, while simultaneously taking into account the(More)
A recent study by Dellwo et al. (under revision) showed that acoustically measurable rhythmic characteristics of speech typically vary significantly between speakers, but there is very little within speaker variability. There is thus evidence that speech rhythm is to a high degree idiosyncratic as has also been shown for music by Palmer & Loehr (2013). In(More)
