Interpreting after the speaker has finished. The interpreter sits with the delegates, listens to the speech and renders it, at the end, in a different language, generally with the aid of notes. In the modern world consecutive interpreting has been largely replaced by simultaneous, but it remains relevant for certain kinds of meetings (e.g. highly technical meetings, working lunches, small groups, field trips).
Well-trained interpreters can render speeches of 10 minutes or more with great accuracy.
