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…).
The recording I transcribed was poor quality at best, so I was pleasantly surprised by how accurately Sonix captured the text. And your editor is absolutely brilliant!
I absolutely love what you guys have done with this. Sonix is literally a magical product that has helped me so much already and I will be using this for a long time coming.
Sonix provided the best transcription of all the platforms I have tested so far.
This software is still the best one out there for the German language.
The best service available for my language (Czech) - thank you very much for saving me a LOT of work!
I love Sonix.ai. They're fast and clean in transcription; they give 98% accuracy in your transcript. I enjoy every of my experience with Sonix...
I wouldn't have been able to pass my course without this technology. I was able to get two A's thanks to this program!
