(CI), the interpreter starts to interpret after the speaker pauses; thus much more time (perhaps double) is needed. Customarily, such an interpreter will sit or stand near the speaker. Consecutive interpretation can be conducted in a pattern of short or long segments according to the interpreter's preference. In short CI, the interpreter relies mostly on memory whereas, in long CI, most interpreters will rely on note-taking. The notes must be clear and legible in order to not waste time on reading them. Consecutive interpreting of whole thoughts, rather than in small pieces, is desirable so that the interpreter has the whole meaning before rendering it in the target language. This affords a truer, more accurate, and more accessible interpretation than where short CI or simultaneous interpretation is used. An attempt at consensus about lengths of segments may be reached prior to commencement, depending upon complexity of the subject matter and purpose of the interpretation, though speakers generally face difficulty adjusting to unnatural speech patterns. On occasion, document sight translation is required of the interpreter during consecutive interpretation work. Sight translation combines interpretation and translation; the interpreter must render the source-language document to the target-language as if it were written in the target language. Sight translation occurs usually, but not exclusively, in judicial and medical work. Consecutive interpretation may be the chosen mode when bilingual listeners are present who wish to hear both the original and interpreted speech or where, as in a court setting, a record must be kept of both. When no interpreter is available to interpret directly from source to target, an intermediate interpreter will be inserted in a relay mode, e.g. a Greek source language could be interpreted into English and then from English to another language. This is also commonly known as double-interpretation. Triple-interpretation may even be needed, particularly where rare languages or dialects are involved. Such interpretation can only be effectively conducted using consecutive interpretation. Simultaneous Simultaneous interpretation (SI) has the disadvantage that if a person is performing the service the interpreter must do the best they can within the time permitted by the pace of source speech. However they also have the advantages of saving time and not disturbing the natural flow of the speaker. SI can also be accomplished by software where the program can simultaneously listen to incoming speech and speak the associated interpretation. The most common form is extempore SI, where
