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.
Thank you for all of your help with my dissertation!!! Ya'll rock!!
Sonix is top class. I would highly recommend Sonix. Especially working in a multi-lingual environment like the European Parliament.
Sonix is by far the best transcription tool I have ever used.
The whole thing is the best I've ever seen! I was amazed at how well this worked at transcribing and translating!
Very cool and fascinating too. Ahh the power of algorithms. I can tell you that I love the overall UI experience because it's pretty, dumbed down, and very easy for me to use. I've done a lot of radio and this service would be invaluable for that kind of work.
