Full context:   Consecutive interpreters, in order to be accurate, used a specialized system of note-taking which included symbols, abbreviations and acronyms. Because they waited until the speaker was finished to provide interpretation, the interpreters then had the difficult task of creating from these notes as much as half an hour of free-flowing sentences closely matching the speaker's meaning. Palazchenko cites Anton Velleman [de], Jean Herbert and the Kaminker brothers as skilled interpreters, and notes one unusual case in which André Kaminker interpreted a speech by a French diplomat who spoke for two and a half hours without stopping.
