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
Sonix's transcription and translation features are stunningly accurate, I'm very impressed.
Impressed at how seamless Sonix makes editing transcripts. This is so much easier and more enjoyable than manually writing an entire transcript myself.
Blown away by what it does! Accuracy, ease of use, affordability, simple straightforward interface with well thought out additional tools and functions. Superb!
The fact that your service can export text as subtitles and can match the subtitles to the paragraphs in the transcript is just great! Also, the text editor is just awesome. The fact it bonds text and timing in the video so I can check and compare what was pronounced and what was recognized is truly fantastic.
I’ve been using your transcription software for about a year now. I just wanted to let you guys know that I think it is incredible. I have tried many alternatives, and none of them have been able to match the accuracy of Sonix!
