I would be interested in hearing others views on how exact you are in transcriptions, especially transcribing audio. I find myself editing out verbal placeholders (um, er, etc) and places where someone begins a sentence, stops and rephrases.
One tape I am transcribing is that of two brothers discussing family history, and they continually interrupt each other, and talk over each other, which makes it difficult to transcribe perfectly.
The tape has been digitized so future generations will be able to actually hear the words.
When it comes to transcribing letters, I am much more devoted to accuracy. Though the grammar and spelling errors are often painful.
