Domain Adaptation in Low-Resource Perso-Arabic ASR with XLSR-53 Pre-Training

Self-supervised pre-training could effectively improve the performance of low-resource automatic speech recognition (ASR). However, existing self-supervised pre-training are task-agnostic, i.e., could be applied to various downstream tasks. Although it enlarges the scope of its application, the capacity of the pre-trained model is not fully utilized for the ASR task, and the learned representations may not be optimal for ASR. In this work, in order to build a better pre-trained model for low-resource ASR, we propose a pre-training approach called wav2vec-S, where we use task-specific semi-supe

Research goal: What is the impact of domain adaptation on the WER of low-resource Perso-Arabic ASR models when pre-trained with multilingual self-supervised models (e.g., XLSR-53) and fine-tuned on domain-specific labeled data?
