Chuchotage is a kind of interpretation where a specialist interprets for 1-2 people into one language. The interpreter stands or sits directly beside you and simultaneously whispers the translation of the speech in the ear.
Chuchotage is used where the majority of a group speaks the source language, and a minority does not. It requires no equipment, but may be done through a microphone and headphones.
Bech interpreters will guarantee professionalism and discretion.
