Sonix is a very user-friendly platform, and they are very transparent about what is included in the monthly fee... It's transcribed very fast and is quite accurate.
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.
Incredibly fast return! Amazingly accurate transcription and exceptionally affordable!
I have absolute admiration for the impressive transcription done to 3 short YouTube videos. It is truly amazing how accurately it recorded the correct words and so well paragraphed...
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!
Faster than my captioning department and so easy to create subtitles!
I love the efficiency, accuracy, and simplicity of going through the transcript to edit and then save it into word. Seamless.
Awesome and I was really shocked when I saw how carefully my mp3 file was transcribed!!
