I found out out you guys because I had to do some transcribing for me yearbook class and my friend recommended you guys. It was a very easy process and it took hours off the time I had to actually had to transcribe it. The timing made it very easy to go back in the recording, this is the best feature in Sonix.
I was surprised in the accuracy from the audio to script. Out of 3 transcripts, only one had to be adjusted. 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.
Works very well with Arabic voices.
Sonix saves me 60% of the time editing. No more manual trascription nightmare with writing down timecodes, and sending emails. I think you are changing the game here! Bravo :)
