In the Voice Dream Reader app, you can select a mispronounced word, type in the correct pronunciation, hit a play button to check how what you typed is pronounced by the reader, and then save that pronunciation. This would be a useful feature in Audemic.
Yes, this is a necessity. I have only tried this out on one paper, and within the first section, I found that I needed to keep going back and listen to the same passage several times because of mispronounced words or abbreviations that made it impossible to follow what the passage was about to the point that just reading the text myself would be more efficient even though I read extremely slowly (hence my investigation into this service). I am currently using the free version, but unless this kind of feature is added, I won't be upgrading to the paid version.
