What customers say about Sonix's automated transcription 
I'd give Sonix a 10 mainly due to the accuracy.
Time is money, and that is exactly what Sonix is saving. Time! So it's worth every penny!!
I love Sonix. It's accurate, intuitive, friendly and simple to use for the technically inept like me! I typically use it for English but we used it this time in French and it was great too.
The fact that your service can export text as subtitles and can match the subtitles to the paragraphs in the transcript is just great! Also, the text editor is just awesome. The fact it bonds text and timing in the video so I can check and compare what was pronounced and what was recognized is truly fantastic.
I tried Sonix, and it’s amazing! Seriously, I think that you will revolutionize journalism.
Wow. SPEED. Nice format, easy to read, liked the time stamps and speaker notification. Not a lot of formatting I had to strip before using. Simple.
