Why users love Sonix
Very high accuracy transcription with noisy tapes / accents. The ability to edit as you listen is incredible. I haven't been impressed with code to this extent since the release of google maps.
I loved my experience cause Sonix has a really good tutorial and it got the words from the audio pretty well. It really did it what I needed really fast, even if it was the first time using it.
So fast, so easy. This has saved me hours for every 20 minutes of recording.
I am very impressed with your program. The recording was not crystal clear and yet I received a perfect transcription...Wow! I would recommend this to anyone.
I LOVE Sonix.
The highest accuracy I have ever achieved through similar services.
My transcript work flow is so fast now. It takes me half the time it used to. So glad i found you :)
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...
