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.
Sonix is easy to use. Ridiculously easy. And even though the accuracy wasn't perfect it saved several days in a typical transcription cycle and the hourly cost we usually pay.
