What customers say about Sonix's automated transcription 
I had been using Dragon voice recognition software, but Sonix eliminates that step all together. I absolutely love Sonix.
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 wouldn't have been able to pass my course without this technology. I was able to get two A's thanks to this program!
Was using another software before, but their prices went up. Your prices are better and the transcription seems more accurate. I also like that you automatically take out all of the filler words - um, you know, etc.
It really accelerated my work and I was amazed by the accuracy, especially given that the video featured only non-native speakers.
Very cool and fascinating too. Ahh the power of algorithms. I can tell you that I love the overall UI experience because it's pretty, dumbed down, and very easy for me to use. I've done a lot of radio and this service would be invaluable for that kind of work.
