Abstract

fetched live from OpenAlex

Second language (L2) pronunciation is one of the most challenging skills to master for adult learners. Accented pronunciation is part of the expression of speakers’ identity, but it could potentially give issues in comprehensibility. Explicit pronunciation instruction from language instructors is often unavailable due to limited class time. Imitating native speakers’ utterances can be done independently from classroom learning, but the absence of feedback makes it difficult for learners to improve their skills. This project takes a multidisciplinary, multimodal approach to pronunciation teaching and learning through a series of video resources, available at http://enunciate.arts.ubc.ca/ . These videos combine external images of a speaker’s head with ultrasound images of their tongue to demonstrate the pronunciation of various sounds. In addition to examples of sounds in isolation, a strong focus to this point has been on the pronunciation of Japanese sounds, with pronunciation instruction incorporating explicit awareness of tongue movements and insights from articulatory phonology. Further stages of the project will include real-time interactive ultrasound tongue visualization and comparative prosody visualization, both of which provide biovisual feedback to L2 learners.

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.
