What customers say about Sonix's automated transcription 
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.
Gobsmackingly amazing! As a software developer of 40 years I know quality when I see it. An amazing product and a pretty damn good web-site to back it all up also. Totally staggered at the accuracy, especially when multiple voices contribute to a meeting.
The transcript came through almost word perfect from a video file. Your system is absolute MAGIC!
I was especially impressed with the quality when it comes to other accents as most other companies can only give a good machine transcript if it is a US accent. Sonix is amazing and I have nothing but good things to say. Thank you for providing this service!
One of the best sites/services on the Internet I've ever tried.
You guys saved me hours of work, reduced my stress level the moment I started and saw the first result coming in.
