What customers say about Sonix's automated transcription 
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 has revolutionized my life! I’m so thankful for the service you provide. It’s been amazing.
I tried 3 other tools online and I can say that sonix blows them out of the water. I was very impressed with the ease of use, the % of words correctly translated and how simple it was to make edits to the translation.
Gobsmackingly amazing! As a software developer of 40 years I know quality when I see it. An amazing product and a pretty damn good web-site to back it all up also. Totally staggered at the accuracy, especially when multiple voices contribute to a meeting.
Sonix is top class. I would highly recommend Sonix. Especially working in a multi-lingual environment like the European Parliament.
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.
