Continual Adaptation for Pacific Indigenous Speech Recognition
Researchers have explored methods to adapt speech foundation models for low-resource Pacific Indigenous languages, addressing data scarcity and the risk of catastrophic forgetting. Their empirical study investigated the effects of data volume, adaptation strategies like LoRA, and representational drift on these models. The findings indicate that adapting to linguistically distant languages causes significant internal representational drift, creating a dilemma between plasticity and stability. While LoRA shows initial promise, it struggles with catastrophic forgetting in sequential learning scenarios, highlighting the need for specialized adaptation techniques for underrepresented languages.
