Besides, particular English was most intelligible to participants with high certain English familiarity. This study investigated how Taiwanese listeners judge the English speech intelligibility of Taiwanese and Indonesian speakers. Thirty Indonesian speakers and thirty Taiwanese speakers participated in this study. Ninety Taiwanese listeners were recruited to judge speech intelligibility. The recording and judging process used the TOCS+ software (Hodge et al., 2009). The software provided 124 contrast items of minimal pairs for the recognition task, including contrast of syllable shape, vowels, and consonants. The listeners' judgments were then analyzed by the TOCS+ software automatically. It was found that Taiwanese English speaker is more intelligible to Taiwanese listeners. The variables that predict intelligibility for Indonesian speakers are syllable shape contrast item correct (SSIC) and consonant item correct (CIC), while Taiwanese speakers' SSIC and vowel item correct (VIC) did not predict intelligibility. Only CIC predicts intelligibility. Both groups made similar errors in consonant voicing. The study's findings contribute to the teaching materials for the English preparation of students who will study abroad.

The study focuses on cross-language perception of selected stops and fricatives among Hausa speakers who have little exposure to Malay, and Malay speakers who have no exposure to Hausa. The primary goal of this study is to examine how Hausa and Malay speakers perceived non-native stops and fricatives that are absent in their native language. Hausa language has a combination of plosives and implosives which involves the use of different airstream mechanisms in their production. Malay speakers who do not have any experience of implosives may find it difficult to discriminate between implosives and plosives, and to produce implosives accurately. In contrast, Hausa speakers may have difficulty discriminating between labial stops and fricatives in Malay as this distinction is not present in Hausa. Forty-five Hausa native speakers and forty-five Malay native speakers were recru...

Methodology A survey was sent to 382 dairy farmers to acquire information on the relevant risk factors associated with SCM. Results The average herd prevalence of SCM among the 189 respondents (response rate 49.5%) was 29%. Farmers who had herds with a low prevalence (<20% cows with individual somatic cell count (ISCC) >2 ¥ 10 5 cells/mL) more frequently wore gloves during milking (26% vs 62%), used individual paper towels for udder preparation (16% vs 62%), fed cows directly after milking (47% vs 87%) and more frequently treated cows with high ISCC (69% vs 80%) than farmers who had herds with a high prevalence of SCM (>30% cows with ISCC >2 ¥ 10 5 cells/mL). The latter more often used selective dry cow therapy (52% vs 24%), compared with low prevalence herds. Conclusion The prevalence of SCM in this cross-sectional study is comparable or lower than reported in other studies from North America and the European Union. The outcome provides a benchmark for the current focus of the NSW dairy industry on the management practices associated with a low prevalence of SCM, such as wearing gloves, using paper towels and feeding cows directly after milking.
