Why users love Sonix
It was excellent and almost entirely spot on with transcription.
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!!
What I was able to do with Sonix was amazing. Transcribed and translated in minutes on remote Guatemalan WiFi!
The speech to text was fast and very accurate.
I tried 3 other tools online and I can say that sonix blows them out of the water. I was very impressed with the ease of use, the % of words correctly translated and how simple it ...
I was amazed at how accurate Sonix is.
The best service available for my language (Czech) - thank you very much for saving me a LOT of work!
