Abstract

fetched live from OpenAlex

Este trabajo constituye un primer intento de elaboracion de un modelo del cambio que incorpora tanto teorias de produccion y percepcion del habla como los resultados de los estudios de la adquisicion de las segundas lenguas. Sobre la base de las primeras, se propone una distincion entre micro y macro variacion, es decir, entre variacion articulatoria no prominente o prominente desde un punto de vista perceptual. Sobre la base de las segundas, se elabora un modelo de categorizacion de la variacion que se apoya en el supuesto de que los aprendices realizan un proceso de clasificacion de equivalencia, en el cual comparan sistematicamente su sistema de sonidos con el de la lengua a la que estan expuestos (Flege 1995). Se argumenta aqui que, en una situacion de variacion y cambio sucede algo semejante y que la incorporacion de la nocion de clasificacion de equivalencia, tomada de los modelos de adquisicion de segundas lenguas permite dar cuenta de por que ciertos cambios siguen una direccion en una comunidad y no en otra. La propuesta se ilustra con distintos procesos de variacion y cambio del espanol de Argentina como asi tambien con trabajos sobre otras variedades del romance (como el frances o el siciliano) y de la adquisicion de segundas lenguas.

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.
