In consecutive interpretation, the interpreter sits with the participants. At suitable points, the interpreter translates into the other language.
In simultaneous interpreting, the interpreter translates while the participants talk. The interpreter usually sits in a soundproof box and translates the message simultaneously through a microphone. As simultaneous interpreting is tiring, interpreters usually work in pairs.
In whispered interpretation, the interpreter sits close to a few participants and translates for them in a low voice. In some cases, the interpreter uses a microphone and those listening use headphones.
We agree on the equipment to be used in advance.
