ArtNet: A JEPA-Like Articulatory Predictive Framework for Robust Zero-Shot Phoneme Recognition

2026-06-15 · Source: Artificial Intelligence · Field: Technology & Digital — Artificial Intelligence & Machine Learning, Natural Language Processing · Depth: Expert, quick

Summary

ArtNet is a novel framework designed for robust zero-shot phoneme recognition, addressing the fragility of direct acoustic-to-symbol mapping caused by language-specific variations. Inspired by joint-embedding predictive architecture (JEPA) in vision, ArtNet employs a structured feature prediction task based on articulatory features to enhance acoustic robustness. The framework integrates an articulatory predictor, which extracts universal articulatory representations from self-supervised learning (SSL) features, with a variational information bottleneck (VIB) to effectively suppress language-specific variations. Evaluated on seven unseen languages, ArtNet, particularly when combined with its proposed vector-space inventory alignment (VSIA) strategy, significantly outperforms competitive baselines. It achieves a 20.56% relative reduction in phoneme error rate (PER) and a 7.01% reduction in phoneme feature error rate (PFER).

Key takeaway

For NLP Engineers developing robust cross-lingual speech systems, ArtNet offers a significant advancement in zero-shot phoneme recognition. You should consider integrating articulatory feature prediction and variational information bottleneck techniques to mitigate language-specific acoustic variations. This approach, especially with vector-space inventory alignment, can substantially reduce your phoneme error rates in unseen languages, improving model generalization and deployment efficiency.
