Truly amazing. Saved me hours of work. And about 95% accurate which is great for a South African accent recording.
I absolutely love what you guys have done with this. Sonix is literally a magical product that has helped me so much already and I will be using this for a long time coming.
Sonix is the best transcription program I've ever used. It was almost error-free. I wish I could have used it longer!
Amazed by the software even in quite mixed audio!
I love your product. I saw the results, and was hooked. Your website is brilliant. SO very easy to navigate and utilize. Your product is game-changing for my business.
The experience is fantastic, the system is easy to use, and transcription quality in different languages is unbeatable. Sonix is the best system I've tried so far...and I know one thing or two about languages/translation and voice recognition.
