abstract = "Cross-linguistic studies of early vocabulary acquisition have shown that despite a general similarity in developmental patterns, different languages are learned at different rates1,6. Danish-learning children, for instance, lag behind a number of other languages in their receptive vocabulary development, knowing about 100 fewer words at age 1;3 than children acquiring other languages. This finding has generally been attributed to the complex phonetic structure of Danish, characterized by a uniquely large inventory of vowel-like sounds. This results in indistinct syllable and word boundaries, which might hinder word segmentation and acquisition1-5. To explore this hypothesis empirically, we used online measures of language processing to investigate to what extent contoids (obstruents and nasal/lateral consonants) and vocoids (vowels and semivowels) play a differential effect on processing words in context. Using the looking-while-listening procedure7, we measured accuracy and latency of children{\textquoteright}s gaze at yoked pairs of pictures as they listened to speech naming one of the two objects on screen. As stimuli, we selected frequently occurring Danish nouns and child-directed expressions with different vocoid-to-contoid ratios, yielding four experimental conditions in which target words and carrier phrases varied from more “consonantal” to more “vowel-like”. We hypothesized that if a higher ratio of vocoids makes word segmentation (hence processing) harder, then we would expect lower accuracy and longer processing times with vocalic target words, especially in the {\textquoteleft}vocoid-carrier-phrase plus vocoid-target{\textquoteright} condition. Our results point indeed to a differential effect of contoids and vocoids on language processing in Danish. A higher rate of vowel-like sounds in a sentence results in lower accuracy and delayed response in word recognition. These outcomes constitute early empirical evidence supporting the possibility that a complicated phonetic structure might be the reason for the observed delay in Danish-learning children{\textquoteright}s vocabulary development.References:(1) Bleses, D., Vach, W., Slott, M., Wehberg, S., Thomsen, P., Madsen, T. & Basb{\o}ll, H.
