Typically, while performing Simultaneous Interpreting, the interpreter sits in a booth wearing a pair of headphones and speaks into a microphone. Strictly speaking, "simultaneous" is a misnomer: the interpreter cannot start interpreting until he or she understands the general meaning of the sentence. Depending for example, on how far apart in the sentence to be interpreted the subject and the verb are located, the interpreter may not be able to utter even a single word until he or she has heard the entire sentence!
