Detecting Self-Repairs from Spontaneous Speech with Prompt Ablation Across LLMs and Fine-Tuned Encoder

This work compares the capability of generative LLMs under a five-condition prompt ablation against a fine-tuned DistilBERT token classifier at detecting self-repairs and suggests that a locally deployable encoder, given sufficient in-domain annotation, is a more plausible route to clinical self-repair detection than s...
