Acoustic Characteristics Anticipate Effect out of Not familiar Dutch Vowels from the Mature Australian English and you can Peruvian Language Audience

Browse suggests that the size of the following code (L2) vowel catalog in line with the newest native (L1) directory make a difference to this new discrimination and you may purchase of L2 vowels. Different types of non-native and you may L2 vowel perception identify you to naive listeners’ non-local and you can L2 perceptual designs can be predict of the matchmaking in the vowel directory proportions within L1 plus the L2. Particularly, that have a smaller L1 vowel list as compared to L2 impedes L2 vowel impact, and have now a bigger one to commonly encourages they. Yet not, the second Words Linguistic Effect (L2LP) model determine that it is this new L1–L2 acoustic relationship one to expect low-native and you may L2 vowel effect, aside from L1 vowel directory. To check the consequences out of vowel collection dimensions against. acoustic functions to the low-local vowel impression, we opposed XAB discrimination and categorization of 5 Dutch vowel contrasts between monolinguals whose L1 consists of way more (Australian English) or fewer (Peruvian Spanish) vowels than simply Dutch. Zero effect of code history are discover, suggesting you to definitely L1 catalog proportions by yourself did not make up overall performance. Alternatively, players in both vocabulary organizations was basically far more exact in discerning contrasts which were predicted getting perceptually effortless based on L1–L2 acoustic matchmaking, and you may had been reduced precise to own contrasts as well predict are difficult. After that, cross-words discriminant analyses predict listeners’ categorization patterns which in turn predict listeners’ discrimination difficulty. Our performance show that listeners with larger vowel stocks frequently stimulate several local groups since reflected when you look at the lower accuracy scores for specific Dutch vowels, if you’re listeners having a smaller sized vowel collection seem to have highest precision results for those same vowels.
