What customers say about Sonix's automated transcription 
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.
Truly amazing. Saved me hours of work. And about 95% accurate which is great for a South African accent recording.
I was simply awed by speed and accuracy of your transcription service.
I love how accurate the software is! The way you can play audio as you go through the text or click on any part of the text to hear the audio is amazing.
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 saves me 60% of the time editing. No more manual trascription nightmare with writing down timecodes, and sending emails. I think you are changing the game here! Bravo :)
