What customers say about Sonix's automated transcription 
Your software is absolutely mind blowing. It is worth every penny!
The best service available for my language (Czech) - thank you very much for saving me a LOT of work!
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!
Sonix is easy to use. Ridiculously easy. And even though the accuracy wasn't perfect it saved several days in a typical transcription cycle and the hourly cost we usually pay.
You saved me! I got everything done in three days and I was sure it will take me a month.
Great product. Been waiting for this.
