What customers say about Sonix's automated transcription 
The entire process is extremely straightforward and what I liked most was the accuracy of the transcriptions and translations. I must say, I had some doubts as to what the quality would be like since it was in French, but I was not disappointed in the least.
It really accelerated my work and I was amazed by the accuracy, especially given that the video featured only non-native speakers.
In one word? FAN-TAS-TIC!! The possibility to split the transcript to subtitles AND split them! THAT IS FANTASTIC!!
The fact that your service can export text as subtitles and can match the subtitles to the paragraphs in the transcript is just great! Also, the text editor is just awesome. The fact it bonds text and timing in the video so I can check and compare what was pronounced and what was recognized is truly fantastic.
Your app is amazing. Seriously, I'm blown away by the technology. The speed, accuracy, and the fact that you can play the audio and that it highlights the transcript in sync.
I am thrilled with the level of accuracy and the easy if which I am able to listen to and adjust the transcript. It’s very user friendly.
