What customers say about Sonix's automated transcription 
My first trial was a video interview with a woman with an Eastern European accent, and I thought there was no way your system would render a good transcriptionābut it was amazingly accurate!
Seriously the best transcript Iāve ever seen. And the synchronized editor is amazing. I will be using again and I will be sharing with my friends :)
Awesome and I was really shocked when I saw how carefully my mp3 file was transcribed!!
I had tried several other software that worked poorly, and was so impressed how well Sonix worked!
I am LOVING Sonix! The price, accuracy, create your own library, check marks when something is completed. I am so glad I found the service.
The process was super easy. I liked that you can upload video file without stripping away the audio first to do it, this of course saves production time. Great job overall for sure!!!
