False starts...

As people are less concise as speakers than as writers, they often make false starts and repeat a word or phrase before they get their point across. Transcribe false starts and repetitions; omitting such elements of spoken language is an error, just as is cleaning up poor grammar. The editor may have to delete some false starts and repititions to make the transcript easier to read, but those that are important either to meaning or to potrayal of the speaker should be retained.
