What customers say about Sonix's automated transcription 
Of all the programs that do this, I found you the best!
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!
AMAZING!! Seamless. Quick. Very accurate. Easy to use. Time stitching. The ease of assigning speakers to paragraphs and making new paragraphs are all amazing!
I’m stunned how much easier it makes life. I worked on documentary films and it cost us a fortune to have the interviews transcribed. The idea that this exists is mind-boggling to me.
I had tried several other software that worked poorly, and was so impressed how well Sonix worked!
I have been a dialogue system researcher for half a decade now. I had build my own app for doing the transcriptions. Sonix was clearly better than what I had. I made the switch!
