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.
This is the greatest transcription service I've ever seen. I am so pleased with the results and I am recommending your services 100 out of 10.
I’m stunned how much easier it makes life. I worked on documentary films and it cost us a fortune to have the interviews transcribed. The idea that this exists is mind-boggling to me.
The best service available for my language (Czech) - thank you very much for saving me a LOT of work!
My transcript work flow is so fast now. It takes me half the time it used to. So glad i found you :)
I am thrilled with the level of accuracy and the easy if which I am able to listen to and adjust the transcript. It’s very user friendly.
The interface and editor experience were great. I also like the way you handle speaker identification and naming. Pretty slick. Nice timestamp frequency / formatting too.
Sonix is top class. I would highly recommend Sonix. Especially working in a multi-lingual environment like the European Parliament.
