I’ve used it for a while in German and in English and I was impressed, too, with its recognition performance. Even the small and therefore fast language models perform decently. However, a major downside is that it doesn’t do punctuation, new lines, capitalization, and similar. This means that you have to edit a lot of the recognized text by hand, which obviously spoils the fun. Having said that, the front end code is in python and you can easily hack it. With a small handful of lines of code I was able to address some of these issues somewhat.
