What customers say about Sonix's automated transcription 
The recording I transcribed was poor quality at best, so I was pleasantly surprised by how accurately Sonix captured the text. And your editor is absolutely brilliant!
I used 30 min free demo for my Google Meeting recording. It is fabulous. I am shocked how Sonix managed to be so accurate.
After trying a number of MP3 transcribers, I am most impressed with Sonix! It was easy to use and was much more accurate than any of the others that I tried.
I had tried several other software that worked poorly, and was so impressed how well Sonix worked!
You guys are the best...hands down!
One of the best sites/services on the Internet I've ever tried.
