I’ve now used Sonix.ai twice, and find the service simple and accurate. It’s exactly what I’ve been looking for to get text from audio and video recordings.
Very high accuracy transcription with noisy tapes / accents. The ability to edit as you listen is incredible. I haven't been impressed with code to this extent since the release of google maps.
The accuracy for the translation was the best from all the other sites and apps I tried.
Time is money, and that is exactly what Sonix is saving. Time! So it's worth every penny!!
You guys saved me hours of work, reduced my stress level the moment I started and saw the first result coming in.
What I was able to do with Sonix was amazing. Transcribed and translated in minutes on remote Guatemalan WiFi!
Sonix is quick and easy to use! It's efficient and transcriptions were very close to perfect - only a little editing needed!!
Sonix is top class. I would highly recommend Sonix. Especially working in a multi-lingual environment like the European Parliament.
