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.
I was amazed by your accuracy. What I used were not very good recordings. One with an American accent, another one Australian and many background noises. The transcript exceeded my expectations.
What I loved about the transcription is that it is fast and it's also highly accurate.
I really like it. Easy to use, very accurate, and easy to correct when it is not. A truly super program, and I would recommend it to anyone.
Sonix is the best transcription program I have worked with.
I love how easy it is – it saves me so much time transcribing – I can just pull out the main points of interest from the transcription.
