Liaison interpreting is a form of consecutive interpreting that takes place in dialogue situations, in which there are two or more parties speaking different languages, and the interpreter is physically present and interprets into both languages. This paper analysed three most common liaison interpreting settings (business dialogues, visits and tours, banquets and receptions) in local context from perspectives of setting-specific challenges and expectations in each setting, and summarizes the role of liaison interpreters as a “mediator”, which means the interpreter plays an active and flexible role to facilitate the communication. The paper then proposes that the liaison interpreting training should adopt a task-and-scenario-based approach, help students build communicative and cross-cultural competence and establish the awareness of professional ethics and the code of conduct through case analysis, discussion and debate.
