What customers say about Sonix's automated transcription 
My transcript work flow is so fast now. It takes me half the time it used to. So glad i found you :)
I love it! It basically nailed every word.
I tried 3 other tools online and I can say that sonix blows them out of the water. I was very impressed with the ease of use, the % of words correctly translated and how simple it was to make edits to the translation.
Really fast to transcribe our audio files with high accuracy, we just had to correct some small words. I like the layout of the website, how pleasing to the eye and easy it is to edit your files, nothing was complicated and I wasn't ever 'stuck' on something and didn't know where to click etc, it was my first time ever using something like this and it was a breeze!
It’s super easy to use and I was so impressed how fast the transcription came back. I love that you can listen to the recording while following along with the transcripts. I also like you can download the transcripts.
The experience is fantastic, the system is easy to use, and transcription quality in different languages is unbeatable. Sonix is the best system I've tried so far...and I know one thing or two about languages/translation and voice recognition.
