arXiv:2606.06794v1 Announce Type: new Abstract: Retrieval-augmented generation (RAG) successfully grounds large language model (LLM) outputs in trusted documents, but factual grounding alone is insufficient for sensitive peer-support health communication. In domains such as HIV peer support, responses must also be accessible, stigma-free, empathetic, and tailored to the recipient. This paper presents TA-RAG, a lightweight, prompt-based tone-aware RAG framework that embeds explicit tone control into a RAG pipeline without requiring model fine-tuning. We operationalise tone across four core comp
The increasing deployment of large language models (LLMs) in sensitive applications necessitates more sophisticated control mechanisms beyond basic factual grounding, particularly in healthcare and peer-support domains.
This development addresses a critical limitation of current AI-driven communication by incorporating explicit tone control, making AI more suitable for empathetic and nuanced interactions in sensitive fields.
AI systems can now be designed for peer-support health communication that is not only factually accurate but also accessible, stigma-free, and empathetic, without requiring expensive model fine-tuning.
