As the name implies, Simultaneous Interpreting involves the interpreter and the primary speaker(s) talking in a relatively uninterrupted manner. The interpreter renders an interpretation in real-time. Some settings may call for the use of special audio equipment (listening device for parties receiving an interpretation and microphone for the interpreter) or chuchotage, in which the interpreter simply renders the interpretation in a low, whispering voice to the party receiving the interpretation. The chuchotage method may at times benefit from the use of headphones for the interpreter.
The primary advantage of Simultaneous interpreting is time-efficiency. Since there is no consecutive turn-taking or pausing for utterances to be rendered. Simultaneous is used in situations where communication is exclusively (or primarily) one-way.
