I was simply awed by speed and accuracy of your transcription service.
The title says it all. Sonix is the simplest, the most accurate transcription service I have ever tried. Even quiet or muffled speech is perfectly produced. If you need one, this is it!
Truly amazing. Saved me hours of work. And about 95% accurate which is great for a South African accent recording.
Sonix transcription service has dramatically reduced the time I need to spend on clients' interviews. Tremendous help!
No joke, this is the best service out there for qualitative research that involves a lot of audio primary data, and I’ve tried a lot of alternatives.
Very high quality transcription - very accurate - only took a quick scan/sweep to manually correct/clean up the text.
I tried Sonix, and it’s amazing! Seriously, I think that you will revolutionize journalism.
Found you through Google. Super easy to use. Transcribed 98% correctly even though it was not a great audio file.
