What customers say about Sonix's automated transcription 
The accuracy for the translation was the best from all the other sites and apps I tried.
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.
Great product. Been waiting for this.
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.
I have been a dialogue system researcher for half a decade now. I had build my own app for doing the transcriptions. Sonix was clearly better than what I had. I made the switch!
Sonix is top class. I would highly recommend Sonix. Especially working in a multi-lingual environment like the European Parliament.
