After trying a number of MP3 transcribers, I am most impressed with Sonix! It was easy to use and was much more accurate than any of the others that I tried.
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.
I was especially impressed with the quality when it comes to other accents as most other companies can only give a good machine transcript if it is a US accent. Sonix is amazing and I have ...
I was surprised in the accuracy from the audio to script. Out of 3 transcripts, only one had to be adjusted. Perfect!!
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!
Incredibly fast return! Amazingly accurate transcription and exceptionally affordable!
I really like it. Easy to use, very accurate, and easy to correct when it is not. A truly super program, and I would recommend it to anyone.
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.
