None that I can remember specifically but it happens a lot. The subtitle text will be something like, “are you sure?” and Captain Picard would say something like, “are you ABsolutely positive?” And I think Brent Spiner added a lot of Data-isms that weren’t in the transcripts.
I think most shows do it. Why would a company pay someone to transcribe when they can just pay someone to line up the audio with the transcript in 1/10th of the time?
