Easy to use and surprisingly accurate.
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.

Your transcription tool is amazing. It's easy to use and gave me a great result.
It was super easy, affordable, and accurate!
Very cool and fascinating too. Ahh the power of algorithms. I can tell you that I love the overall UI experience because it's pretty, dumbed down, and very easy for me to use. I've done a lot of radio and this service would be invaluable for that kind of work.
