Customer reviews of Sonix's automated transcription 
Surprisingly accurate transcription across a number of European accents (Yorkshire, Scottish, Oxford, Italian!)
I love, love, love this service! Sonix is amazing! I plan to use the transcripts I've gotten so far to update the content of my podcast so that it will aid in SEO on my website. Very, very useful!
Sonix is easy to use. Ridiculously easy. And even though the accuracy wasn't perfect it saved several days in a typical transcription cycle and the hourly cost we usually pay.
Sonix can quickly generate a transcript and it has cut my workload by half.
