Pit or phit? The production of English aspirated stops by speakers of Dutch

This thesis examines whether native speakers of Dutch can aspirate unvoiced word-initial plosives in English as a second language and if they are able to do so to the same degree as native speakers of English. 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...Show moreThis thesis examines whether native speakers of Dutch can aspirate unvoiced word-initial plosives in English as a second language and if they are able to do so to the same degree as native speakers of 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
