Abstract

fetched live from OpenAlex

Abstract The main goal of this study was to determine whether the geminate-singleton consonant length contrast attrites across three different generations of Farsi-English-speaking bilinguals living in Canada. The secondary aim of the study was to shed light on the role of universal phonetic factors on the process of geminate-singleton length contrast attrition in the same population. The effect of manner/class of sounds and voicing was examined as predictors of geminate attrition in eight Farsi-English-speaking bilinguals living in Toronto forming three categories of generations: first generation, 1.5 generation and second generation. The 1.5 generation category distinguishes children of Iranian immigrants who had acquired Farsi as their first language and came to Canada between the ages of five to fourteen from second generation heritage speakers of Farsi. The productions of the bilinguals were compared with the productions of three homeland variety controls. A word-naming task, which included 108 words was conducted. Using Praat software, 2398 tokens were acoustically analyzed. Attrition was defined in terms of changes in mean duration of geminates relative to their singleton counterparts, percentage of geminate-singleton degemination, and category overlap. Mean durations were then analyzed using a 3-way, mixed-model, repeated-measures ANOVA. Results showed that geminates attrite across different successive generations. Moreover, there was some evidence to suggest that geminate realization across generations patterns with typological patterns previously reported, showing that universal phonetic principles such as aerodynamic constraints/articulatory difficulty and acoustic/perceptual salience also constrain geminate realization in bilingual Farsi-English speakers. However, there was no evidence to suggest that more marked geminates suffer a higher degree of attrition. This is the first study to examine the attrition of a typologically marked contrast, which considers the role of universal phonetic principles, markedness in an understudied bilingual community across different generations.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
