What customers say about Sonix's automated transcription 
Was using another software before, but their prices went up. Your prices are better and the transcription seems more accurate. I also like that you automatically take out all of the filler words - um, you know, etc.
The speech to text was fast and very accurate.
I tried a few transcription services and I found yours to be clearly superior. The results were more complete and accurate.
I’m stunned how much easier it makes life. I worked on documentary films and it cost us a fortune to have the interviews transcribed. The idea that this exists is mind-boggling to me.
The UI is da bomb with so many great features including the one where I can highlight a passage and download as a clip. So very useful! It’s editing and transcription combined!!
I found out out you guys because I had to do some transcribing for me yearbook class and my friend recommended you guys. It was a very easy process and it took hours off the time I had to actually had to transcribe it. The timing made it very easy to go back in the recording, this is the best feature in Sonix.
