Your product is incredible. I love it!
I love the software and it makes my life so much easier...you cannot believe!
Sonix is faster and better than YouTube at making captions for my videos!
Very high quality transcription - very accurate - only took a quick scan/sweep to manually correct/clean up the text.
I am very happy to have found a transcription service that provides such a high percentage of perfect content.
Sooooooooooo easy to use and accurate.
Sonix is a godsend service boosting my productivity and alleviating a major source of stress in my life.
I loved that Sonix supports so many languages. I've been working on a project that involves speakers of 6 different languages and it allows me to translate everything into English ...
