What customers say about Sonix's automated transcription 
We love transcribing with Sonix. Your interface for subtitle editing is excellent.
I heard about you from my friend. I found my transcription to be almost exactly what is in the audio file. Love it...continue what you are doing. Sonix is excellent. I appreciate that.
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.
Sonix is simple and very easy to use and the results were very nearly perfect. I would definitely recommended the site to anyone who asks me.
I had tried several other software that worked poorly, and was so impressed how well Sonix worked!
It really accelerated my work and I was amazed by the accuracy, especially given that the video featured only non-native speakers.
