@liaizon Years ago I transcribed a director talking about his film. Since this was part of the promotional materials, I cleaned up all the false starts, random sounds, and fixed the grammar.
The director came back furious that I'd changed what he said, because every single word out of his mouth was a treasure, so I re-transcribed it accurately with all that stuff back in, including random sounds and the grammar that's just a mess when its written down.
They ended up not using any of it.
