What customers say about Sonix's automated transcription 
This software is still the best one out there for the German language.
I'm very impressed about the accuracy. The transcript needs a little editing, but just minor correction. I think the interface is straightforward and user-friendly. I also like the audio-transcript matching playback functionality. I've been very deterred to use recording during my interviews because it takes a tremendous amount of time to transcribe.
The accuracy, that's what I like the most.
I have absolute admiration for the impressive transcription done to 3 short YouTube videos. It is truly amazing how accurately it recorded the correct words and so well paragraphed as well.
Sonix is simple and very easy to use and the results were very nearly perfect. I would definitely recommended the site to anyone who asks me.
Amazed by the software even in quite mixed audio!
