What customers say about Sonix's automated transcription 
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 really enjoyed how quickly and accurate the transcription system was. Will definitely use again in the future. I have recommended you to a friend.
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.
Your product is amazing, I love so many features including the video capture on the side, ability to change the transcript as you go, highlighting, downloading audio files... SEARCHING TRANSCRIPTS
The entire process is extremely straightforward and what I liked most was the accuracy of the transcriptions and translations. I must say, I had some doubts as to what the quality would be like since it was in French, but I was not disappointed in the least.
Way better than other transcription services I've tried. It will save me a lot of time. I'd recommend it to everyone I know.
