What customers say about Sonix's automated transcription 
Sonix is light years ahead of all the other solutions I researched and tried!
Sonix is top class. I would highly recommend Sonix. Especially working in a multi-lingual environment like the European Parliament.
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 have tested your product among others, and I have to say, Sonix provides the best results, a really great product!!!
Truly amazing. Saved me hours of work. And about 95% accurate which is great for a South African accent recording.
Sonix is easy to use. Ridiculously easy. And even though the accuracy wasn't perfect it saved several days in a typical transcription cycle and the hourly cost we usually pay.
