Performed by interpreters who translate what a speaker is saying without the use of special equipment (booth, headsets, microphones, etc.) at intervals of 5-10 minutes. The interpreter and speaker take turns: the interpreter listens to the presentation and takes notes during the period of time established and then provides the audience with a summary in their own language.
This type of interpreting is used when only one foreign language is required and normally for short, formal events, such as press conferences or for formal round tables.
