Whispering interpreting or ‘chuchotage’ is usually only used when one or two people do not understand the source language. It is a portable and convenient way of transferring the message, since there are no headphones, booths, or microphones required.
During this type of interpreting, the interpreter is seated next to the meeting participants and simultaneously renders the interpretation in a low voice. That is why it is most commonly used during social events, dinners or small one-to-one meetings.
This form of interpreting would not be recommended if more than two people require interpretation as it would create too much noise and distraction. It would only be recommended for short meetings as the technique of whispering and speaking continuously in a low voice strains the vocal chords.
