I’m really dazzled by your system. I have never seen something so accurate. You push the level higher than Otter and available for French language!
I love it! It basically nailed every word.
Sonix is a godsend service boosting my productivity and alleviating a major source of stress in my life.
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.
I’m convinced that Sonix at the moment is the best transcription service existing anywhere in the world.
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.
It was super easy, affordable, and accurate!
One of the best sites/services on the Internet I've ever tried.
