What customers say about Sonix's automated transcription 
I thought it was absolutely amazing, flawless.
Great website. Love the drag & drop option. Very accurate too!
I loved how accurate you are even in Dutch!
I've tried several different digital software packages and nothing has even approached giving me a usable transcription. The results from Sonix are the best I've seen. And fast. I'd given up on having my recordings automatically transcribed. No more.
I tried a few transcription services and I found yours to be clearly superior. The results were more complete and accurate.
No joke, this is the best service out there for qualitative research that involves a lot of audio primary data, and I’ve tried a lot of alternatives.
