Researchers have conducted a case study comparing seven Parameter-Efficient Fine-Tuning (PEFT) variants for per-patient Automatic Speech Recognition (ASR) systems designed for individuals with dysarthria. The study focused on a single Hungarian male speaker with severe post-stroke dysarthria, evaluating methods like LoRA, QLoRA, AdaLoRA, DoRA, LoHA, VeRA, and VB-LoRA on two base ASR models: Whisper Large V3 and Qwen3-ASR-1.7B. Results indicated that attention-projection adapters significantly improved accuracy, with LoRA being chosen for its simplicity and cost-effectiveness over other variants like QLoRA and LoHA, despite LoHA showing promise. While full fine-tuning achieved the highest accuracy, a LoRA adapter offered comparable performance at a fraction of the storage cost. AI
IMPACT This research could lead to more efficient and accessible per-patient ASR systems for individuals with speech impairments.
