What customers say about Sonix's automated transcription 
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.
This is the greatest transcription service I've ever seen. I am so pleased with the results and I am recommending your services 100 out of 10.
