Abstract

This study explores the role of dialect prompting in Generative Artificial Intelli-gence (GenAI) systems through a comparative analysis of prompts written in Standard Greek and the Corfiot dialect. The research examines how linguistic variation in prompts influences AI-generated responses in terms of language structure, stylistic characteristics, semantic content, and cultural representation. To carry out our study, we relied on five original prompts written in Standard Greek and the same five prompts translated into the Corfiot dialect. The prompts represent different communicative functions, including storytelling, instruction generation, descriptive narration, advisory requests, and conversational interaction. The generated responses are evaluated using a mixed-methods approach combining quantitative and qualitative analysis. Quantitative indicators include response length, average sentence length, lexical diversity, and the representation of dialect-specific vocabulary, while qualitative analysis focuses on semantic consistency, stylistic adaptation, dialectal sensitivity, and the incorporation of culturally specific linguistic elements. The results indicate that dialect prompting produces measurable differences in AI-generated content compared to prompting in the standard language variety. Such differences mainly concern response style, lexical selection, discourse organization, and the incorporation of culturally lo-calized linguistic elements. Our findings contribute to research on dialect-aware AI, prompt engineering, sociolinguistics, and digital cultural heritage preservation by highlighting the significance of regional language varieties in human–AI inter-action and contemporary natural language generation systems.
