What customers say about Sonix's automated transcription 
I was especially impressed with the quality when it comes to other accents as most other companies can only give a good machine transcript if it is a US accent. Sonix is amazing and I have nothing but good things to say. Thank you for providing this service!
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 :)
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!
I really like it. Easy to use, very accurate, and easy to correct when it is not. A truly super program, and I would recommend it to anyone.
I loved how accurate you are even in Dutch!
Sonix is the best transcription program I have worked with.
