I tried Dragon Naturally Speaking a couple of years ago.  (After
breaking a wrist in a cycling accident, I figured it might be easier
than one-hand typing, which wasn't true in the case of typing
programming code with lots of curly brackets, indentation, etc.)

Speech-to-text software works best after a training session, in which
the software asks the speaker to read a known text, to calibrate the
software.  I'm not sure how it might work to calibrate for voices on
recordings, but it may be that the software can learn during a
proof-reading process.  Your success for oral history recordings may
depend on the uniqueness of each speakers voice, and the length of
each recording.  (Lots of short recordings of many different speakers
would tend to be harder.)
