Closed Caption solution

Query from a friend – Her government agency is looking for a way to do closed captioning for video (because of 508 compliance). She saw a posting I did about using Dragon Naturally Speaking software to transcribe long interviews…and I suspect that is not necessarily the answer for her.

So how do you or your organization handle transcribing for CC?
I know I’ve seen what appears to be live (and at times inaccurate) transcription.

Thanks in advance.
