Why users love Sonix
Very high accuracy transcription with noisy tapes / accents. The ability to edit as you listen is incredible. I haven't been impressed with code to this extent since the release of google maps.
I tried 4 other services, and Sonix is the easiest to use, most accurate, and more reasonably priced for the quality.
Researched and did trials of at least 12 other services. Chose Sonix because of accuracy and simplicity.
Your app is amazing. Seriously, I'm blown away by the technology. The speed, accuracy, and the fact that you can play the audio and that it highlights the transcript in sync.
It is so easy to use, very intuitive. Everything 'works'. It is so simple and hassle-free.
I'm a journalist and I'm finding that Sonix is a very valuable tool.
Sonix is by far the best transcription tool I have ever used.
I am VERY happy with the transcription! There were a few glitches, but 98% great.
