Verbatim typing is used when transcribing things such as police interviews, court transcripts, focus groups, etc.  It is a very specific style of typing which sets out every um and ah, every mumble, stumble and stutter.  All contractions are typed as such (doesn't, can't, I dunno, yeah, nah, etc).  It is a very useful and necessary tool in the correct circumstances.  However it has no place in medical transcription.
