Aspiration was measured in word-initial unvoiced plosives /p, t, k/ using Voice Onset Time (VOT). Influence of sex, age, age of onset of the second language, and self-reported general pronunciation ability in English were also examined. Native Dutch VOT generally lies between 0-20ms, while native English VOT is anywhere between 50-100 ms. Using recordings from 19 participants who read both Dutch and English sentences out loud, it was found that participants increased their aspiration with an average of 10 ms when switching from Dutch to English. The analysis also shows that two participants out of 19 had an average VOT at a native-like level (>50 ms). Further investigation showed that sex, age, and age of onset did not influence VOT. Participants who graded their general pronunciation abilities with an 8 or higher did show a bigger increase in VOT, but there was no correlation to higher VOT in English when compared to other speakers. Other results showed that /p, t, k/ were not aspirated to the same extent, with /t/ being aspirated significantly more and /p/ significantly less. Lastly, the co-existence of words in both English and Dutch did not significantly alter the VOT, only when words started with /k/ did aspiration significantly improve when the exact word also existed in Dutch. These results conclude that native speakers of Dutch increase aspiration and can aspirate to a native-like degree while speaking English. Any defining factors of the participants who were able to do so are not available due to the limited sample size.Show less

With the use of an online questionnaire, I wanted to find out whether native speakers of Farsi are better at categorizing the English word-final plosive voicing contrast than native speakers of Dutch, because native speakers of Farsi have native-language experience with the same contrast in the same position. The results show that both the Dutch and the Farsi group were relatively successful in distinguishing this contrast, but the Farsi group categorized it significantly better. The results of the Dutch group are in line with previous literature that indicate that perception of an L2-contrast is supported by native-language experience with the same contrast in other positions. Additionally, the results of the Farsi group imply that perception of an L2-contrast becomes even better when there is native-language experience with the same contrast in the same position.Show less

The Perceptual Assimilation Model stipulates that we analyse sounds in a second language in terms of those from the first based on articulatory similarities. It predicts that if two sounds in a speaker’s second language are analysed as the same sound in the first, they will be difficult to distinguish. Proposing that Dutch speakers analyse Russian /tj/, /tʃ/, and /tjj/ as Dutch [tʃ], I used an AXB-task to systematically investigate Dutch speakers’ ability to distinguish the Russian sounds /t/ and /d/, the coronals /t/, /tj/, /tʃ/, and /tjj/, and the sibilants /ʃ/ and /ʃj/. Since stress affects the vowel quality of the vowel following plain and palatalised consonants differently, I also investigated the effect of stress. Last, participants indicated how easy it was to distinguish the contrast. Analyses revealed that the Dutch participants performed worse than the Russian speakers on /tj/-/tʃ/, /tj/-/tʃ/, /tʃ/-/tjj/, and /ʃ/-/ʃj/, while still having an accuracy of well above .50. Initial stress was only found to negatively influence discrimination of /tj/-/tjj/. The Russian speakers also performed worse on the /tj/-/tjj/ contrast, meaning results on this contrast are to be interpreted with caution. These results show that, while Dutch speakers experience difficulty with perceptually distinguishing sounds not available in Dutch, this difficulty is attenuated. This is important, because it confirms that Dutch learners of Russian should focus on these sounds, while at the same time suggesting that they already have a good head start.Show less
