Simultaneous interpretation is when a speech, or other form of oral communication, is interpreted as it is spoken so as not to disrupt the flow of a speaker. It is sometimes mistaken as Simultaneous Translation; however, the act of conveying speech from one language to another orally is known in the linguistic industry as interpreting.
Generally simultaneous interpreters work in pairs, and sit in a sound-proof booth while having access to a video feed of the speaker. They will then interpret the speech to listeners in an uninterrupted flow via microphones or headsets.
Specialized equipment, which can be provided upon request, is almost always required to maintain seamless communication through simultaneous interpretation services.
