What customers say about Sonix's automated transcription 
I am very happy with the quality of the transcriptions! Having tried numerous other services, none can compare based on the quality for the value.
Sonix is AWESOME and extremely accurate. This software has it all. I wish that all of the software that I use on a daily basis had the complete and thoughtfully created functionality of Sonix!
Was using another software before, but their prices went up. Your prices are better and the transcription seems more accurate. I also like that you automatically take out all of the filler words - um, you know, etc.
Very high accuracy transcription with noisy tapes / accents. The ability to edit as you listen is incredible. I haven't been impressed with code to this extent since the release of google maps.
My transcript work flow is so fast now. It takes me half the time it used to. So glad i found you :)
The accuracy for the translation was the best from all the other sites and apps I tried.
