Sonix is faster and better than YouTube at making captions for my videos!
The accuracy of the initial transcription was better than any I've used to date, and making adjustments was very simple.
I really like it. Easy to use, very accurate, and easy to correct when it is not. A truly super program, and I would recommend it to anyone.
