Instances of This new Scenario try predicted to possess PS which from Similar Condition getting AusE listeners

Based on full LDA classifications, one another listener organizations are expected to come across Equivalent Circumstances whenever identifying Dutch /?-?/, because these vowels are acoustically similar to line of indigenous phonemes. not, in accordance with the stepwise DAs both Dutch /?/ and you will /?/ happen F1 resemblance so you can AusE /?/, F2 similarity to help you AusE /?:/ and /?/, and you may F3 resemblance to help you AusE /?/, /?:/ and /?/. Yet not, considering group proportions (elizabeth.g., F2: Dutch /?/ > AusE /?:/, 80% and you will /?/ 15%, Dutch /?/ > AusE /?/, 95% and you may /?:/, 5%), it is forecast you to definitely AusE listeners, against Subset Condition, is identify these phonemes as a result of the due to the lower acoustic overlap within F2 and you will F3 signs. Having said that, PS listeners try predicted to demonstrate straight down discrimination accuracy as compared to AusE listeners because of a higher acoustic overlap across all the about three acoustic size and tend to be subsequent expected to identify each other vowels because PS /i/, /e/, and you will /u/.

In accordance with the full Weil and you can stepwise habits, AusE listeners is actually predict to get the Dutch /a-?/ a bit challenging to detect as these vowels was basically categorized across a couple or higher AusE vowel groups, if you find yourself PS audience was predict to come across New Circumstances because of the mainly mapping the new audio relative to PS /a/.

In sum, in the event that predictions based on listeners‘ L1 vowel inventories dimensions try borne aside, AusE listeners, whose vowel inventory is actually larger than that of PS, are expected to possess highest discrimination precision than just PS audience to own all five Dutch contrasts. As an alternative and you can pursuing the L2LP’s acoustic hypothesis, if the acoustic differences when considering L1 and you may L2 determine low-local sound effect, one another listener groups‘ discrimination dilemmas will be give similar overall performance. That is, both listener organizations are expected to stand this new, Similar, and you may Subset Problems. To evaluate these contrastive hypotheses, naive AusE listeners‘ XAB discrimination and you may categorization of 5 Dutch vowel contrasts (/a-?/, /?-i/, /y-?/, /i-y/, and you can /?-?/) are compared to those regarding naive PS listeners stated within the prior education (Escudero and you will Wanrooij, 2010; Escudero and you can Williams, 2011).


Twenty-two monolingual AusE students aged 18–45 years (Mage = 24.1 years; 11 females) participated for course credit at Western Sydney University. Participants were born and raised in Greater Western Sydney, and reported no experience with Dutch or any hearing impairment.

Non-native vowel categorization data from the same AusE listeners were compared to non-native vowel categorization data from 40 PS monolinguals (20 females) from Lima, Peru reported in Escudero and Williams (2011). Participants ranged in age from 18 to 30 years 2 , and reported no knowledge of Dutch or hearing impairment. XAB discrimination data from our AusE listeners was then compared to discrimination data of 22 PS listeners reported in Escudero and Wanrooij (2010). Listeners were monolinguals aged 17–28 years (Mage = ; 10 females) born and raised in Lima, Peru their entire life and reported no knowledge of Dutch.

Fellow member studies range on the establish investigation was carried out in conformity for the Peoples Search Ethics Panel (HREC), Western Sydney College or university, acceptance amount H9373.

Stimulus and you will Processes

Both sets of players first accomplished a two-alternative forced possibilities XAB discrimination activity followed by a good nonnative categorization task. Brand new auditory stimulus towards XAB discrimination activity have been 20 obviously brought tokens of each and every of four Dutch vowels /a/, /?/, /?/, /i/, /y/, and you will /?/, extracted from recordings developed by 20 local Practical Northern Dutch sound system (ten girls) from inside the monosyllabic utterances in the a neutral non-phrase /sVs/ consonantal perspective stuck in this a company phrase (Adank mais aussi al., 2004b). Throughout the XAB task, listeners heard about three musical consecutively and you will was then requested to suggest perhaps the earliest voice (X) sounded similar to the next (A) otherwise 3rd (B) sound of the hitting 1 of 2 yellow squares (viz. “2” and you may “3”) exhibited towards the a computer monitor. There clearly was an enthusiastic inter-stimuli interval of just one.2 s, that was selected because it is long enough to lead to phonological activation (Werker and Logan, 1985; Van Hesse and you can Schouten, 1999; Escudero and you will Wanrooij, 2010), and you will an enthusiastic inter-demonstration period of 0.5 s adopting the participant’s options. The latest experiment are conducted for the Praat and you will consisted of four reduces (one for each and every contrast-/a-?/, /?-i/, /y-?/, /i-?/, and you will /?-?/) that has had 80 products for each and every.
