Abstract

fetched live from OpenAlex

Mnong Râlâm is a South Bahnaric language (Austroasiatic) that is traditionally described as preserving a voicing contrast in onset obstruents, contrary to other languages of the Mnong/Phnong continuum. Acoustic results yield evidence that this voicing distinction is less robust than previously suggested and is redundant with a register contrast realized on following vowels through modulations of F1 at vowel onset (and more limited variations of F2 and voice quality). A perception experiment also shows that F1 weighs heavier than closure voicing in identification. The existence of a language in which voicing and register are redundant allows us to revisit previous models of registrogenesis. It suggests that the acoustic properties of register may develop and become distinctive while voicing is still present rather than as a direct consequence of devoicing. The unexpected discovery of register in Mnong Râlâm also challenges previous reconstructions of Proto-South-Bahnaric, in which only voicing is postulated, based on hitherto limited available descriptive materials.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
