Voice Under Revision: Large Language Models and the Normalization of Personal Narrative

ArXi:2604.22142v1 Announce Type: new This study examines how large language model rewriting alters the style and narrative texture of personal narratives. It analyzes 300 personal narratives re Across models and prompt conditions, LLM rewriting produces a consistent pattern of stylistic normalization. Function words, contractions, and first-person pronouns decrease, while vocabulary diversity, word length, and punctuation elaboration increase. These shifts occur whether the prompt asks the model to "improve" the text or simply to "rewrite" it.
