Why users love Sonix
Transcription was almost perfect!!
The accuracy, that's what I like the most.
Sonix is top class. I would highly recommend Sonix. Especially working in a multi-lingual environment like the European Parliament.
Wow very cool. Sonix is so awesome. There will be huge demand for this. The editor will be really good for team sharing. Such a great platform.
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 transcription—but it was amazingly accurate...
Very high quality transcription - very accurate - only took a quick scan/sweep to manually correct/clean up the text.
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.
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.
