What customers say about Sonix's automated transcription 
Truly amazing. Saved me hours of work. And about 95% accurate which is great for a South African accent recording.
EASY AND QUICK, VERY VERY ACCURATE!!
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.
I love how easy it is – it saves me so much time transcribing – I can just pull out the main points of interest from the transcription.
Fast, easy transcription. Also the ability to edit in the software with the recording before exporting is a great feature. I have already recommended you to a friend.
After trying a few other trial software, Sonix was by far the best and most correct.
