Consecutive interpretation is rendered as “short CI” or “long CI”. In short CI, the interpreter relies on memory, each message segment being brief enough to memorize. In long CI, the interpreter takes notes of the message to aid rendering long passages. These informal divisions are established with the client before the interpretation is effected, depending upon the subject, its complexity, and the purpose of the interpretation.
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.
Consecutively interpreted speeches, or segments of them, tend to be short. Fifty years ago, the CI interpreter would render speeches of 20 or 30 minutes; today, 10 or 15 minutes is considered too long, particularly since audiences usually prefer not to sit through 20 minutes of speech they cannot understand.
Often, if not previously advised, the source-language speaker is unaware that they may speak more than a single sentence before the CI interpretation is rendered and might stop after each sentence to await its target-language rendering. Sometimes, however, depending upon the setting or subject matter, and upon the interpreter’s capacity to memorize, the interpreter may ask the speaker to pause after each sentence or after each clause. Sentence-by-sentence interpreting requires less memorization and therefore lower likelihood for omissions, yet its disadvantage is in the interpreter’s not having heard the entire speech or its gist, and the overall message is sometimes harder to render both because of lack of context and because of interrupted delivery (for example, imagine a joke told in bits and pieces, with breaks for translation in between). This method is often used in rendering speeches, depositions, recorded statements, court witness testimony, and medical and job interviews, but it is usually best to complete a whole idea before it is interpreted.
Full (i.e., unbroken) consecutive interpreting of whole thoughts allows for the full meaning of the source-language message to be understood before the interpreter renders it in the target language. This affords a truer, more accurate, and more accessible interpretation than does simultaneous interpretation.
