Simultaneous interpretation may also use portable equipment or “bidule”, that works similarly to tour guide systems.
The difference with traditional interpretation equipment is that here there is no booth. The audio of a speaker is streamed to a simultaneous interpreter wearing headphones with a microphone.
The interpretation takes place and is streamed to the audience in real time. Listeners also wear headphones connected to wireless receivers.
Portable equipment systems are efficient to run meetings with few participants or when participants have to change venue during the event. Events that can take advantage of this kind of service are factory visits, training courses, and small business meetings.
