arXiv:2606.31642v1 Announce Type: new Abstract: Southern Bantu languages are spoken by over 80 million people, yet current foundation ASR models still produce zero-shot WER above 100%, which limits practical use in education and public services. We addressed this gap with a tone conditioned curriculum framework for 6 Southern Bantu languages that combined hybrid difficulty scoring, gated adapters driven by tonal statistics and staged curriculum training. We trained on a community corpus and tested transfer to NCHLT to measure robustness beyond matched evaluation. Results revealed clear interac
This research addresses a critical gap in AI's practical application for underserved language communities, reflecting a growing global push for equitable AI development and reduced digital divides.
Improving speech recognition for low-resource languages has significant implications for education and public services, particularly in regions previously excluded from advanced AI benefits.
The development of effective tone-conditioned curriculum learning for challenging languages can enable more inclusive AI tools and reduce dependency on models trained primarily on dominant languages.

Access to AI-powered services like educational tools and government interfaces will significantly improve for Southern Bantu language speakers.
Increased digital literacy and economic opportunities could emerge within communities previously marginalized by language barriers in technology.
The success of this approach could catalyze similar efforts for thousands of other low-resource languages globally, leading to a more linguistically diverse AI landscape and reduced digital colonialism.
