Note-taking is an important skill for interpreters as it helps reduce stress, assist short-term memory, and facilitate logical delivery of information. There are two main ways interpreters take notes - diagram noting and vertical noting. Diagram noting uses a tree structure with main ideas and supporting ideas while vertical noting lists main ideas and supporting ideas separately. Effective interpreter notes focus on key words and concepts rather than full sentences through techniques like abbreviations. Note-taking extends an interpreter's memory and enhances their focus on the speaker, which is important for consecutive interpreting.
