What customers say about Sonix's automated transcription 
Sonix's transcription and translation features are stunningly accurate, I'm very impressed.
Sonix is AWESOME and extremely accurate. This software has it all. I wish that all of the software that I use on a daily basis had the complete and thoughtfully created functionality of Sonix!
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.
Your UI and UX was one of the best I've seen. And I've seen a lot of them. Clean, simple, and pretty easy to edit.
Sooooooooooo easy to use and accurate.
I was surprised in the accuracy from the audio to script. Out of 3 transcripts, only one had to be adjusted. Perfect!!
