Michel Foucault’s thought of power believes that everyone within a relational network plays a role and holds certain power in hand to stabilize and strengthen the function of the network.Liaison interpreters,clients,and the communication context are three most important components of the communication network.During the interpreting process,interpreters hold some power in hand and they will use this power when necessary through the action of empowerment.In this paper,with analysis on liaison interpreters’empowerment under different occasions,three kinds of empowerment can be concluded;liaison interpreters empower themselves;liaison interpreters empower clients;interpreters empower context.It also proves that proper empowerment could facilitate the communication while over-empowerment could hinder the communication.
