What customers say about Sonix's automated transcription 💘

4.98 rating from 197 reviews
Easy to use and surprisingly accurate.
Sonix is AWESOME and extremely accurate. This software has it all. I wish that all of the software that I use on a daily basis had the complete and thoughtfully created functionality of Sonix!
I love how quick, affordable and accurate it is, but what I like MOST is that the words are highlighted as the recording speaks them!
What I loved about the transcription is that it is fast and it's also highly accurate.
Your app is amazing. Seriously, I'm blown away by the technology. The speed, accuracy, and the fact that you can play the audio and that it highlights the transcript in sync.
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!
