This is dependent upon the duration, format and nature of the request. With most assignments that run 90 minutes or longer, two interpreters will be necessary. Sometimes even short assignments require two interpreters depending on the difficulty of the content. Interpreters work as a team when they interpret and they also switch off to maintain accuracy of the interpretation and avoid fatigue. Interpreting is taxing, both physically and mentally. [Interpreter fatigue is a major cause of inaccuracy, and even top professionals need to rest their minds and vocal cords at regular intervals.] Interpreter count is ultimately at Graham’s discretion and we will work with you to ensure appropriate coverage.
