I loovvvve that the audio is transcribed so quickly.
After trying a number of MP3 transcribers, I am most impressed with Sonix! It was easy to use and was much more accurate than any of the others that I tried.
My first trial was a video interview with a woman with an Eastern European accent, and I thought there was no way your system would render a good transcription—but it was amazingly accurate!
I was surprised in the accuracy from the audio to script. Out of 3 transcripts, only one had to be adjusted. Perfect!!
