What customers say about Sonix's automated transcription 
Thank you for all of your help with my dissertation!!! Ya'll rock!!
It's incredibly fast, and it sets the timing for subtitles perfectly. I dread having to time everything myself, and with Sonix I can do that just by pressing Enter!
I had tried several other software that worked poorly, and was so impressed how well Sonix worked!
I was especially impressed with the quality when it comes to other accents as most other companies can only give a good machine transcript if it is a US accent. Sonix is amazing and I have nothing but good things to say. Thank you for providing this service!
Awesome and I was really shocked when I saw how carefully my mp3 file was transcribed!!
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.
