Claims

C1strongest claim

Our method significantly bridges the performance gap, achieving on average a relative Word Error Rate (WER) reduction of 29 % over monolingual baselines. Our models also outperform state-of-the-art multilingual models across major benchmarks, including Common Voice and Fleurs.

C2weakest assumption

The iterative self-improvement stage assumes that pseudo-labels generated by the initial distilled model are sufficiently accurate and do not introduce systematic errors that compound over iterations; this premise is invoked when describing the second stage of refinement on pseudo-labelled data.

C3one line summary

SBPN is a multilingual ASR model for five Nigerian languages that delivers a 29% relative WER reduction over monolingual baselines through teacher-student distillation plus iterative pseudo-label self-improvement.
