Monolingual LoRA language experts, combined by weighted merging (MoLE) or layer-wise knowledge distillation, improve Whisper-based multilingual ASR by about 10-15% relative WER over a plain multilingual LoRA baseline.
With the advent of deep learning techniques, ASR has achieved remarkable suc- cess in various real-world scenarios[1, 2, 3, 4, 5]
