I’ve been using this app to transcribe a large number of letters, some typed and some handwritten. The error rate is good, generally less than 5%. With a couple of OCR programs I was getting error rates on the order of 20% on typed copy, and somewhat higher on longhand items.There are some recurring, and now predictable, errors such substituting “the” for “a” about half the time, and rarely recognizing “of” as a word— “if” can be a problem, too. Must have difficulty with labial fricatives! And there are some others that tend to recur, such as not recognizing “Open parentheses, Parenthesis, or Close parentheses” as valid punctuation commands…but it does a good job of recognizing the words, and spelling them correctly! As an annoyance, it’s relatively minor…Overall, I’m happy with its performance, but there’s still room for improvement. It appears to use an AI engine for next-word prediction, but the engine is not as intelligent as it should be…not yet ready to take over the world!
