What customers say about Sonix's automated transcription 
I loved my experience cause Sonix has a really good tutorial and it got the words from the audio pretty well. It really did it what I needed really fast, even if it was the first time using it.
The experience is fantastic, the system is easy to use, and transcription quality in different languages is unbeatable. Sonix is the best system I've tried so far...and I know one thing or two about languages/translation and voice recognition.
I really like it. Easy to use, very accurate, and easy to correct when it is not. A truly super program, and I would recommend it to anyone.
The transcript came through almost word perfect from a video file. Your system is absolute MAGIC!
You guys saved me hours of work, reduced my stress level the moment I started and saw the first result coming in.
Sonix is amazing. It’s like adding the most brilliant brain to my staff.
