Perceptual assimilation of Dutch vowels by Peruvian Spanish listeners

Many cross-language and L2 speech perception studies have been conducted on English sounds and a limited number of speakers or synthetic tokens have been used for auditory stimuli. The Spanish listeners of the present study were presented with natural tokens of Dutch vowels produced by males and females selected from the corpus reported in Adank (2004) J. Acoust. Soc. Am. 116, 1729-1738. The results show that single category assimilations are common and that certain Dutch vowels frequently assimilate to Spanish diphthongs. Predictions are made for Spanish learners' initial stage in the acquisition of the Dutch vowel system.
