Researchers have developed a new multilingual Automatic Speech Recognition (ASR) framework called Sometin Beta Pass Notin (SBPN) to improve performance for Nigerian languages. The framework uses a two-stage knowledge distillation process, first from monolingual models and then through iterative self-improvement with pseudo-labeled data. This approach achieved an average 29% relative Word Error Rate reduction over baselines and outperforms existing state-of-the-art multilingual models on benchmarks like Common Voice and Fleurs. SBPN is released as open foundation models in two sizes, aiming to provide crucial ASR resources for the region. AI
