What customers say about Sonix's automated transcription 
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.
The whole thing is the best I've ever seen! I was amazed at how well this worked at transcribing and translating!
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.
Sonix is the best transcription program I've ever used. It was almost error-free. I wish I could have used it longer!
I had tried several other software that worked poorly, and was so impressed how well Sonix worked!
Way better than other transcription services I've tried. It will save me a lot of time. I'd recommend it to everyone I know.
