What customers say about Sonix's automated transcription 
I found out out you guys because I had to do some transcribing for me yearbook class and my friend recommended you guys. It was a very easy process and it took hours off the time I had to actually had to transcribe it. The timing made it very easy to go back in the recording, this is the best feature in Sonix.
In one word? FAN-TAS-TIC!! The possibility to split the transcript to subtitles AND split them! THAT IS FANTASTIC!!
The transcription was fast and accurate.
Faster than my captioning department and so easy to create subtitles!
I have a 30-40 minute commute to work and like to dictate memos and other brief documents along the way–but I haven't had an easy way to get them transcribed...until now. Thanks Sonix!
Sonix is by far the best transcription tool I have ever used.
