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.
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.
I love the software and it makes my life so much easier...you cannot believe!
I tried Sonix for the first time and I was astonished by the incredibile conversion accuracy.
The highest accuracy I have ever achieved through similar services.
