What customers say about Sonix's automated transcription 
Sonix is easy to use and high accuracy of the transcriptions. Very pleased!
I loved that Sonix supports so many languages. I've been working on a project that involves speakers of 6 different languages and it allows me to translate everything into English natively, saving me so much time!
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.
Impressed at how seamless Sonix makes editing transcripts. This is so much easier and more enjoyable than manually writing an entire transcript myself.
Sonix is top class. I would highly recommend Sonix. Especially working in a multi-lingual environment like the European Parliament.
