What customers say about Sonix's automated transcription 
Fast and easy, and accurate. And searchable.
Having tried numerous transcription services, this was undoubtedly the best. There were features (such as the synching up of the audio to the words for review) that I hadn’t ever hoped to find.
The level of accuracy and your UI is quite amazing. It allowed me to try the product without having to learn anything new, I was so happy about it I sent the results to a couple of friends because I knew at the moment that this could change the way I work.
Sonix provided the best transcription of all the platforms I have tested so far.
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.
Thank you for this amazing application and program which really saved my life.
