Translation Style Variation across Registers in Machine Translation and Large Language Model Outputs
A Corpus-Based Study of English-to-Chinese Translation
Abstract
This study examines translation style variation across registers in English Chinese outputs from TencentMT, DeepSeek, and ArkLLM. Using an aligned corpus of public speech, legal-diplomatic texts, and news, it compares length ratio, mean sentence length, and connective density through mixed-effects modelling and qualitative analysis. ArkLLM generally produced longer outputs, while TencentMT produced shorter sentences and used more explicit connectives. Register also shaped these patterns, showing that AI translation style varies across systems and communicative contexts.
