What customers say about Sonix's automated transcription 
I have been a dialogue system researcher for half a decade now. I had build my own app for doing the transcriptions. Sonix was clearly better than what I had. I made the switch!
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.
I used 30 min free demo for my Google Meeting recording. It is fabulous. I am shocked how Sonix managed to be so accurate.
It was super easy, affordable, and accurate!
The transcription was fast and accurate.
I've tried several different digital software packages and nothing has even approached giving me a usable transcription. The results from Sonix are the best I've seen. And fast. I'd given up on having my recordings automatically transcribed. No more.
