Contrastive learning boosts accent robustness in ASR systems

Researchers have developed a new method called supervised contrastive learning (SupCon) to improve the robustness of automatic speech recognition (ASR) systems against accent variations. This technique acts as an auxiliary objective during the fine-tuning process, regularizing the model's internal representations without requiring architectural changes or explicit accent labels. Experiments on the L2-ARCTIC benchmark demonstrated significant reductions in word error rates, particularly for unseen accents. AI
