I work with spoken word/oral histories all the time, and it is my
recommendation that to make a digitized preservation copy/master, that it is
done in real-time. I work with both reel-to-reel and cassettes, with speeds
ranging from 15/16ths to 15ips.
I believe there is a requirement to get the best quality from spoken word recordings. In fact, in terms of preservation work, real-time is the only way to go. I'm sorry, it may take longer, but it is worth it.
