What customers say about Sonix's automated transcription 
This is the best software I've used for transcription. Really happy about that!
Easy to use and surprisingly accurate.
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.
Amazed by the software even in quite mixed audio!
After trying a number of MP3 transcribers, I am most impressed with Sonix! It was easy to use and was much more accurate than any of the others that I tried.
So fast, so easy. This has saved me hours for every 20 minutes of recording.
