What customers say about Sonix's automated transcription 
I'd give Sonix a 10 mainly due to the accuracy.
It really accelerated my work and I was amazed by the accuracy, especially given that the video featured only non-native speakers.
After trying a number of MP3 transcribers, I am most impressed with Sonix! It was easy to use and was much more accurate than any of the others that I tried.
Sonix is light years ahead of all the other solutions I researched and tried!
I've used other platforms that don't do a good job at all. Sonix was close to perfect!
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.
