The speech to text was fast and very accurate.
I’m blown away by how accurate it was.
Gobsmackingly amazing! As a software developer of 40 years I know quality when I see it. An amazing product and a pretty damn good web-site to back it all up also. Totally ...
The accuracy of the AI voice recognition is amazing! Sonix is by far the most accurate of the 5 or 6 services that I tested.
It was excellent and almost entirely spot on with transcription.
I tried a few transcription services and I found yours to be clearly superior. The results were more complete and accurate.
Sonix is just so smooth and simple. Love it. No bugs, very intuitive. Oh and your software is surprisingly accurate!
It's incredibly fast, and it sets the timing for subtitles perfectly. I dread having to time everything myself, and with Sonix I can do that just by pressing Enter!
