What customers say about Sonix's automated transcription 
Sonix is a godsend service boosting my productivity and alleviating a major source of stress in my life.
Having tried numerous transcription services, this was undoubtedly the best. There were features (such as the synching up of the audio to the words for review) that I hadn’t ever hoped to find.
Sonix is the best transcription program I've ever used. It was almost error-free. I wish I could have used it longer!
I am a video editor and I found you by trying a few services with free trials. Sonix was far, far superior as well as an easy process to trial enroll.
This software is still the best one out there for the German language.
I love how easy and intuitive it is to use Sonix! I can now put my energy and focus on actual content, instead of going through the tedious and time consuming process of transcribing audio.
