Sonix is so easy to use, and the quality is impressive in almost all languages we have tested so far. Punctuation is especially amazing compared to other platforms, even the tech giants (Google, Microsoft…).
I was cleaning up the transcription of the recording of my Brazilian client. Sonix did a surprisingly good job. Sonix's accuracy in transcription is great.
Sonix's transcription and translation features are stunningly accurate, I'm very impressed.
After trying a few other trial software, Sonix was by far the best and most correct.
The whole thing is the best I've ever seen! I was amazed at how well this worked at transcribing and translating!
I've tried your service, and I love it.
The UI is da bomb with so many great features including the one where I can highlight a passage and download as a clip. So very useful! It’s editing and transcription combined!!
I'm very happy with the experience. The Spanish translations are superb. I'm in awe!
