Cultural Transcreation in Asian Languages with Prompt-Based LLMs

Helena Wu, Beatriz Silva, Vera Cabarrão, Helena Moniz


Abstract
This research explores Cultural Transcreation (CT) for East Asian languages, focusing primarily on Mandarin Chinese (ZH) and the customer service (CS) market. We combined Large Language Models (LLMs) with prompt engineering to develop a CT product that, aligned with the Augmented Translation concept, enhances multilingual CS communication, enables professionals to engage with their target audience effortlessly, and improves overall service quality. Through a series of preparatory steps, including guideline establishment, benchmark validation, iterative prompt refinement, and LLM testing, we integrated the CT product into the CS platform, assessed its performance, and refined prompts based on a pilot feedback. The results highlight its success in empowering agents, regardless of linguistic or cultural expertise, to bridge effective communication gaps through AI-assisted cultural rephrasing, thus achieving its market launch. Beyond CS, the study extends the concept of transcreation and prompt-based LLM applications to other fields, discussing its performance in the language conversion of website content and advertising.
