Why users love Sonix
I've used other platforms that don't do a good job at all. Sonix was close to perfect!
English dictation is very accurate. And the online editor is easy to use. Also it generates SRT files that I can import in my video editors for further processing.
The best thing ever, nothing more to say.
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 initial transcription was better than any I've used to date, and making adjustments was very simple.
I have been a dialogue system researcher for half a decade now. I had build my own app for doing the transcriptions. Sonix was clearly better than what I had. I made the switch!
Amazing for foreign videos that need subtitles. The platform is super easy to use and gave me EXACTLY what I was looking for.
Sonix is by far the best transcription tool I have ever used.
