What customers say about Sonix's automated transcription 
I love, love, love this service! Sonix is amazing! I plan to use the transcripts I've gotten so far to update the content of my podcast so that it will aid in SEO on my website. Very, very useful!
I'd give Sonix a 10 mainly due to the accuracy.
I was surprised in the accuracy from the audio to script. Out of 3 transcripts, only one had to be adjusted. Perfect!!
In one word? FAN-TAS-TIC!! The possibility to split the transcript to subtitles AND split them! THAT IS FANTASTIC!!
I heard about you from my friend. I found my transcription to be almost exactly what is in the audio file. Love it...continue what you are doing. Sonix is excellent. I appreciate that.
Very cool and fascinating too. Ahh the power of algorithms. I can tell you that I love the overall UI experience because it's pretty, dumbed down, and very easy for me to use. I've done a lot of radio and this service would be invaluable for that kind of work.
