The presenter speaks one language but some in the audience speak a different language, You need SIMULTANEOUS INTERPRETATION, and the EQUIPMENT to best provide it.
In this case, the INTERPRETER listens to the speaker and simultaneously interprets the message via a TRANSMITTER to her audience. People in the audience needing interpretation services are wearing RECEIVER HEADSETS that pick up the transmission from the interpreter.
